SIG SAUER Announces Details of Free P320 ‘Voluntary Upgrade’ Program

Last week, SIG SAUER announced that they will be offering a “voluntary upgrade” program to owners of the 500,000 P320 pistols that have been sold since the gun was first introduced. This was prompted by reports that the P320 can fire when dropped. SIG decided to offer an upgraded trigger pack — one they’d designed for the M17 Modular Handgun System — for all P320 pistols that had been sold commercially.

Given the speed at which the reports and SIG’s response happened a week ago, the company needed some time to work out the logistical details. That’s now been done and SIG SAUER will upgrade the pistols free of charge. Here’s how the program will work:

3 Steps To Upgrading Your SIG SAUER P320 Pistol

1. Have your P320 serial number and home address available.

2. Fill out the Voluntary Upgrade Sign-Up Form — one serial number per form submission.

3. SIG SAUER will contact you regarding the best method for you to get your P320 pistol to them.

Once SIG SAUER receives your P320 pistol, they will apply the upgrades, test it, and then return it to you free of charge.

How to locate your P320 Serial Number

Your P320 serial number can be found by looking on the right side of the pistol grip. The serial number will be stamped into the receiver. This number should be entered into the first entry field of the form. SKU will automatically populate if your P320 is on a qualified list of U.S. Domestic consumer serial numbers.

With some exceptions, most U.S. Domestic Consumer P320 serial numbers begin with “58A”, “58B”, or “58C”, followed by six numbers.

– Example: 58Axxxxxx

FREQUENTLY ASKED QUESTIONS

Is my P320 safe in its current configuration?
Yes. The P320 meets and exceeds all US safety standards. However, mechanical safeties are designed to augment, not replace safe handling practices. Careless and improper handling of any firearm can result in an unintentional discharge.

What is the P320 Voluntary Upgrade Program?
SIG SAUER is offering a voluntary program for P320 pistols. This will include an alternate design that reduces the physical weight of the trigger, sear, and striker while additionally adding a mechanical disconnector.

Why is this upgrade happening?
Through additional testing above and beyond standard American National Standards Institute (ANSI)/Sporting Arms & Ammunition Institute (SAAMI), National Institute of Justice (NIJ), Department of Justice (DOJ), Massachusetts (MGL, Chapter 140, Section 123) and other global military and law enforcement protocols, we have confirmed that usually after multiple drops, at certain angles and conditions, a potential discharge of the firearm may result when dropped. Although it is a rare occurrence, with very specific conditions, SIG SAUER is offering an upgrade to all of its current P320 owners.

Does the owner’s manual say it can be unsafe?
The language used in major manufacturer’s owner’s manuals with regard to drop safety is consistently written to warn the user that dropping a loaded firearm is not recommended and could possibly result in an accidental discharge. All precautions should be taken to avoid dropping a loaded firearm. Although extremely unlikely, it is still possible for any loaded firearm to discharge when dropped.

What calibers and models are affected?
Due to the modularity of the pistols, which all share the same trigger group, all calibers and pistol sizes are affected.

      Just so you know, if you are involved in a shooting with a recalled gun, it is all on you. They can call it “voluntarily ” all they want, but this is a recall and in the eyes of the law as well.

        You’re probably one of those guys who believes it’s completely taboo to do any internal modifications to your carry gun, right? Don’t lighten that trigger, the prosecutor will get you!

        Seriously, how would a drop safety issue in any way, shape or form have any bearing whatsoever on an intentional pull of the trigger in a self defense situation?

      4. You sound like a lawyer are you? I have already registered for the “Voluntary recall” as I had problems with mine day one-which Sig fixed.

  2. avatar FlamencoD says:

    Why do they keep claiming it is safe in its current condition? So what if it passes a few soft safety tests, it obviously isn’t safe and that fact has been proven so.

    1. avatar Because says:

      Because it passed the ANSI and SAAMI tested which didn’t require the -30 degree drop failure. Read the FAQ, it’s mentioned in there.

      1. avatar Joe R. says:

        It also didn’t pass the 45 min. in a 375 degree oven test either.

        1. avatar Eric Lawrence says:

          It did pass the “Make Sure the Slide Doesn’t Fly Off the Frame” test…Glock 17M IMPD August 2016.

    2. avatar Gerbs says:

      “So it passed some soft ALL OF THE UNIVERSALLY ACCEPTED SAFETY TESTS THAT THE ENTIRE WORLD USES”, so what?

      There, fixed it for you.

      If you think you know better (which is possible), then please create a SAAMI alternative standard, publish it, and get the global firearms industry to accept it.

  3. avatar AubreyB says:

    “free of charge” – good to hear. But the amount of “our gun is super duper extra safe and these issues were above and beyond anything that could happen in the real world but we’re doing this out of our commitment to our customers” PR bologna makes me roll my eyes like a high school girl. Just take accountability for it, admit you screwed up, fix it for your customers, so we can ALL move on.

  4. avatar CLarson says:

    This is pretty much the same way Springfield Armory did their XD-S recall back when. I went through it and got my gun back in about a month.

    1. avatar JasonM says:

      You must not have sent yours in quickly.
      They took several months to even figure out how to fix it. I knew some people who waited almost a year.

    2. avatar Tom says:

      No, Springfield went ahead and fully recalled the guns, while sig seems content with letting their customers shoot their dicks off unless they go without their gun for a while to get it “upgraded”.

      1. avatar Gerbs says:

        That level of hyperbole is just laughable…

        You wouldn’t be a big Alex Jones fan, would you?

  5. avatar Char says:

    I have two P320s purchased at LGS, the serial number comes back as a Law Enforcement or US govt special program and I am unable to proceed further. (I am not anything special just a person)

    1. avatar Jeremy S. says:

      I think you’re special, Char!

    2. avatar Snarky says:

      Maybe contact Sig instead of posting here? Just a thought.

    3. avatar MG says:

      Sounds like your pistols were meant to be sold as part of the Armed Professional Program at a discount. I understand that Sig will have an online form available for these pistols in a few days. I’m in the same boat, it sucks but I guess that is the price of receiving the discount.

      1. avatar Tim says:

        Same here. Personally, I’m not going to be in any great ‘hurry’ to get this remedied. I’d like several thousand to go back, get upgraded, then drop tested every which way but Sunday, and see what the results are. Luv me some SIGs, but if they gooned it once they could goon it twice.

    4. avatar Char says:

      I contacted Sig directly, they have registered the two P320s manually.

    5. avatar i1uluz says:

      Look on the plastic case, the item number, does it start with a “W”, if so it’s a LEO/Mil discount program item. Sig most likely won’t be happy a retailer sold it at mark up and don’t take this wrong to an unqualified person. Glock has pulled stores who violated their Blue Label program right to sell their pistols. And Sig does not allocate many items to the LEO/Mil program to start with.

  6. avatar Jeremy S. says:

    FYI, since I know it’ll be asked:

    The trigger upgrade slightly improves the trigger pull. I know there is concern that they may have made the trigger pull terrible in order to fix it, but that isn’t the case. In fact, they said most of these changes were due to requests to improve the trigger pull feel by getting rid of the “double click” that some had complained about. That’s basically the only change in the pull. It is now smooth all the way to the break without any initial click sensation prior to the break. The pull weight, travel distance, break, reset feel and distance, reach to the trigger, etc. is effectively identical.

    Second, no FFL is required. You’ll be able to print the shipping label and deliver the box to FedEx/UPS directly or have it picked up, and the gun will be returned directly to you. No transfers are needed for warranty work. It’s already your gun. I’m fairly confident this is the case in all 50 states.

    Third, yes, they need the entire gun plus any other slides and grip frames you may have. All parts — slide, chassis, grip frame — require work.

    1. avatar chedolf says:

      “Third, yes, they need the entire gun plus any other slides and grip frames you may have. All parts — slide, chassis, grip frame — require work.”

      I don’t see anything on the Sig upgrade page about grip modules. I have a new, uninstalled small grip module for my P320 Compact. Now I’m wondering if I need to send that in along with the pistol. Guess I’ll be contacting Sig to find out.

      1. avatar Jeremy S. says:

        They didn’t get super specific, but I think this is clear enough:

        Am I required to send the entire pistol?
        Yes.

        SIG told us that they have to drill a hole or otherwise mill/modify the grip frame to create clearance for the trigger disconnect system.

        1. avatar chedolf says:

          If that’s the case, then none of the replacement grip modules currently being sold will be compatible with “upgraded” P320s. Sig and its dealers would need to warn customers about that.

        2. avatar chedolf says:

          Just got off the phone with a Sig customer service rep. He said existing Sig replacement grip modules will work with the upgraded P320. Asked to confirm the grip module info, he answered “yes, we’re not touching those.”

    2. avatar Mikele Deziell says:

      I’m super confused because I just talked to a Sig Rep yesterday on the phone and he said ONLY the original grip module is needed and I will NOT be required to send in my other sizes of grip modules because the grip itself is NOT being worked on. So which is it? Are they (Sig) just lying now because they don’t want to have to fix every extra grip module out there or what? What’s the truth here? Very fustrating!

      1. avatar Gerbs says:

        Stop.
        Breath.
        Think.

        A miscommunication in a very dynamic (but not life threatening) situation does NOT = “they’re lying to us!!! Conspiracy!!”.

        Most likely SIG does not want to encourage all users to take the gun apart – because some of them will do it wrong, and blame Sig for their screwup. This happens all the time in the firearms industry.

        This does not mean there’s a conspiracy afoot to keep you from getting a working gun. This does not mean they lied when they told you the grip modules will not be modified.

  7. avatar Hannibal says:

    I wonder what the legal distinctions are, if any, between a ‘voluntary UPGRADE’ and that scary word ‘recall’ and how it might effect potential lawsuits.

    1. avatar hrfdez14185 says:

      There’s no difference in the eyes of the law. You use a recalled gun in a shooting or hurt someone, it is all on you.

      1. avatar Robert says:

        Just so you’re aware, if you use an unrecalled gun In a shooting and hurt someone, it’s also on you.

        1. avatar GS650G says:

          Unless you are LE and then it depends.

        2. avatar Robert says:

          Without commentary of your personal feelings for the Law Enforcement Officers in your community, I’m telling you that even for the LE… when you use your weapon and injure someone else, it’s still on you.

        3. avatar gyrfalcon says:

          Is it also on you if you shoot yourself? What about if it’s your big screen TV that gets shot? SIG has to be at fault if your TV gets shot I’m pretty sure.

  8. avatar TanHat says:

    Since some of the upgrades are in the slide and not in the serialized frame, will those people who purchased Caliber X-Change Kits be able to send just a slide in? (Or a second slide with a firearm?)

    1. avatar TanHat says:

      NVM – Sig’s site just loaded for me:

      What about my CAL-X Kits?
      You should send any and all P320 slides with your shipment, as the striker(s) will be replaced, and the slide(s) will need the disconnector cut.

  9. avatar Rimfire says:

    Does the picture show the new, lightweight trigger or is that the old one? Is the frame marked with a dot or anything to identify the upgrade?

    1. avatar Jeremy S. says:

      The bottom picture shows an M17 trigger. This is unlikely to be the production, commercial P320 upgrade trigger. It could be physically the same, but I highly doubt it will be finished in the Army-mandated “neutral” sand/gold/tan color. At any rate, the upgrade trigger will be highly similar in that it will be thinner and completely hollowed out on the rear just like this one. The current P320 triggers, as seen in the lead photo above, are wider front-to-back and aren’t completely hollowed out on the back side. The idea is to reduce its mass.

      You’ll be able to simply look at the trigger itself and tell if it’s an old one or an upgrade one.

  10. avatar TwoJohnsonsAreBetterThanOne says:

    Is the diarrhea color mandatory?

      1. avatar Jeremy S. says:

        No. Two Johnsons guy, please see my comment just above yours.

  11. avatar Sig RetaRd says:

    look at those x-five triggers lol- Glock killer wins again

  12. avatar TruthTellers says:

    I have a better idea for a voluntary upgrade: trade it in for a Glock and its Perfection of a Safe Action trigger.

    1. avatar Bud Harton says:

      Did Glock fix that pesky slide falling off whenever the gun was pointed down yet?

      1. avatar John in AK says:

        Yes, they did. And, more on point, the guns didn’t fire by themselves, unlike with some other brands. . .
        Anything else?

        1. avatar i1uluz says:

          Well they sort of did, when chambering a round, even had a burst fire. But it did pass the drop test. But on the other hand, Glock had the self firing mode FIRST in 1992, Suffolk county PD. They replaced 6 parts. They called it a TSB.

          GLOCK, INC. Technical Bulletin #920403

          April 1, 1992

          Glock, Inc. announces a production change of the firing pin safety system. This has been installed in all production Glock pistols since November, 1991. A voluntary upgrade is being offered to maintain the Glock tradition of ensuring that all of our pistols are up to the latest standards in 21st century Glock technology.

          Most importantly, the components of the new firing pin safety system are not interchangeable with the components of the old system and Glock will always strive towards maintaining this feature of interchangeability while working to ensure future interchangeability.

          The upgraded firing pin safety system consists of: the firing pin, firing pin safety, the extractor, the spring loaded bearing and the trigger bar. The upgraded system is applicable only to Glock pistols with the following serial number ranges :

          Glock 17 – alpha prefixes AA – WF
          Glock 19 – alpha prefixes through WJ
          Glock 20 – alpha prefixes through WW
          Glock 21 – alpha prefixes through XL
          Glock 22 – alpha prefixes through YA
          Glock 23 – alpha prefixes through SK

          The upgraded firing pin safety has a new surface finish making it nearly 100% saltwater corrosion resistant. Also, after rigorous and extensive testing, the new system proves to be more durable and has a longer useful life. Here, as always, Glock is working toward maintaining its standard of perfection.

    2. avatar MG says:

      Some of us already own a Glock and don’t find it to be perfection.

    I think I will just stick with lusting after a Beretta 92 Compact for nowand wait for the rush to subside in five or six years…

  14. avatar John E> says:

    So I have to pull the apex enhanced flatty out and put the old in and send it in huh? 🙄

    1. avatar Chris B says:

      I’m in the same boat, I’ll have to remove mine. Here’s my thought though… I just watched the video on Sig’s site about what the “upgrade” consists of and as far as the drop safety goes, the only thing they’re doing is replacing the trigger. none of the other mods are in relation to the drop fire issue….. So, I remove my Apex trigger, send it in, they put their thinner, lighter trigger on it, I get it back and put my Apex back on it…. I’m in the same boat I’m in now. I think I’ll just hold onto it and not drop it with a round chambered. Seems kinda elementary.

  15. avatar Michi says:

    Test it and send it back… So they’re gonna drop our guns for us huh? Well that’s mighty nice of them…

  16. avatar Moto says:

    Alls wells that ends well. . . But what about international sales? I’m from South Africa and our laws allow only one SD firearm after 6 months of applications and loops to jump through. I know more than a few waiting for licences on P320s and many who own them. They will now go defenceless while they upgrade. If they upgrade. If Sig decides we’re worth it.

    1. avatar Farmer Brown says:

      Yeah, I and a couple of my shooting partners have a stack of P320’s and we live outside the USA. It’s simply not possible to post gun parts in/out of the USA.

  17. avatar Sarah says:

    🚫 whining!
    OMG!! 😛 SOME PEOPLE’S KIDS ARE SO ANNOYING!!
    I ❤ MY P320! I’LL BE SAD TO PART FOR THE TIME OF UPGRADING BUT IT’S NO DIFFERENT THAN WHEN YOUR VEHICLE GETS A FLAT TIRE! YOU DON’T DRIVE AROUND ON THAT SHIT.. CHRIST!

  18. avatar Tom Knapp says:

    When can we expect new sales to include the ” safe” version of the 320?

  19. avatar Mike says:

    Stop the blame game and take responsibility for being stupid and dropping a loaded gun. I remember when I was in the Army the drill sergeants had a way of dealing with soldiers who dropped their weapons.

    First let me say to all the Glock comments, I remember Glock having problems with their pistol when it first came out. I remember reading a couple of wrongful death lawsuits filed against Glock because of their pistol. Don’t get me wrong I own several Glocks and Sigs. Seems the only problem we have with Sig is that it is not “stupid proof”. Let get real about this. Any firearm can go off if drop. The problem is not that the gun can go off, it is that gun owners think that it is alright to drop a loaded gun. We need to remember that as gun owners we have a responsibility to carry and store our firearms in a safe manner. I am glad to see that Sig is dealing with this issue and I will be sending my pistol in for the upgrade because I know that accidents can happen and I want my pistol to be as safe as possible.

    Lets not blame the gun or the manufacturer of the gun because you could not hold on to it.

    1. avatar John in AK says:

      NO, Mike. Not every gun can fire if dropped. In fact, some of the oldest firearm designs in current use cannot, simply will not, fire no matter how far they fall and what surface they fall upon.
      Smith & Wesson has been building drop-safe revolvers since 1899. Colt started building theirs in 1894. Enfield started building THEIRS in 1882.
      Any quality American DA revolver built over the past 100+ years is absolutely drop safe,
      There are other designs available that are equally safe. Most are, however, rather elderly. They were created in a time when guns were durable industrial art, not disposable consumer goods.

      1. avatar Mike says:

        to John in AK

        The only way a gun will not fire is if it is unloaded. I have seen the so called drop safe guns fire when they are not suppose to. I am not saying that every gun will fire if dropped but that there is a chance. Take into account the design and wear on the parts. Show me a gun that will not fire and I will show you a gun what I do not want. My point was not that a gun can fire, but that it is irresponsible to thank that it is alright to go around dropping loaded guns.

        1. avatar John in AK says:

          No. Everyone is entitled to their own opinion, but not to their own facts. You are, simply, wrong.

          But, suit yourself.

      2. avatar JF says:

        So if you drop your gun and something hits the trigger it won’t go off?

        This country is in trouble.

    Between this and this terrible, unreliable and not drop-safe Walther CCP the lesson should be clear; stay away from German handguns.

  23. avatar Dr. Vinnie Boombotz says:

    Any idea about the necessity of the upgrade if I’ve already put an Apex flat trigger in?

    1. avatar Jeff says:

      At least some of the APEX triggers are physically heavier than the stock trigger. They would most likely make this problem worse. Probably why APEX is offering credit for those that want to return theirs. Read into that as you wish.

      Suggest at least weighing what you have versus the stock trigger that comes in around 16.2 grams. While guess it could depend upon where the extra weight is in the trigger it is probably safe to say a physically heavier trigger does not help with this problem.

      I would highly suggest P320 owners take advantage of the upgrade, recall, or whatever you wish to call it. If you have 3rd party trigger components in yours then put it back to factory before sending it in.

      If you don’t have the original parts to put your handgun back to factory components then I’d still send it in anyways. My reading of things is they will still upgrade it, but they make no promises regarding the return of those parts with your upgraded handgun. I don’t think that is a matter of them wanting to toss non-Sig parts, it’s just about process logistics and trying to keep track of parts not normally there. If you reinstall non-Sig parts in your freshly upgraded handgun it will no longer be factory spec so you best know what you are doing and the risks you assume.

      I can imagine that some would figure it wise to wait awhile to see if the new “Gen 3” trigger (I made that up) is better, not be the beta tester of the upgrade process, and allow things to calm down some. If it’s a better trigger that essentially gives you the XM17 or XM18 handgun’s improvements then I can’t imagine not wanting to upgrade.

      If you want to use/carry a firearm with a known safety issue then that’s a risk calculation you’ll have to make and assume. I wouldn’t do it, but that’s my call. I’ve heard the stat based arguments about the risks here and considered them both ways. My personal stance is if I’m going to carry/use a loaded firearm around others beyond myself… then I have a responsibility to ensure that it’s a modern well maintained firearm that’s as safe as it can possibly be. Anything less is irresponsible in my opinion, an opinion I’m sure most liability lawyers would agree with. You do as you feel best, but the two P320’s here are out of service till repaired/upgraded.

      Be safe.

      1. avatar Dr. Vinnie Boombotz says:

        Thanks very much for a thoughtful and detailed response.

      2. avatar OldFed says:

        Just replaced my Apex trigger with the factory trigger and spring. Waiting patiently on my email for the trigger upgrade.

  24. avatar Bob says:

    Some of us have put the apex flat trigger in our p320 does this mean it’s drop safe?

  25. avatar Sy says:

    Just an FYI to anyone that goes through with signing up for this “we swear it’s not a recall.”

    I signed up right away, got zero confirmation emails that the information was received, and now a week later I am getting promotional spam from Sig. Daily.

    Glad to know that they are more interested in selling products than they are in getting the products already sold fixed.

  26. avatar J. Bailey says:

    Okay, lets assume some drunk is pounding on my door at 2am bar closing time. Lets assume he pushes past me with hostile words. Seeing he is not armed but very muscular I put my sig320 away and grab my baseball bat. Lets assume I married in too much haste and she thinks I am about to lower the IQ of her favorite boyfriends.
    In a panic she hits me with the other baseball bat. The gun falls out of my waistband and as it hit’s the floor, it fires and shoots wife dead.
    An off duty policeman was walking by and arrests me and intruder. Intruder has been in prison before and immediately says he saw my shoot my wife.
    If this is California will I ever get out of prison.

    The judge knows in this day and age very few handguns ever fire when dropped. Only the extremely cheap “ring of fire” zink guns, made in a ring around Los Angeles years ago. Or a few very old cheap revolvers when they fall on hammer. (Ruger changed all their authentic western revolvers years ago for this reason. Now to rotate the cylinder you only open the loading gate).

    Note, if you have any old cheap semi auto that is single action with a safety, putting a small piece of modern duck tape on the safety helps keep it on safe, when loose in pocket. Most people carried them with chamber empty. Most were small .22 rimfires and a person could rack the slide very fast with practice.
