The SIG SAUER P320 XFive Legion is everything that made the P320 XFive great, only prettier.

The original 2018 verison of the P320 XFive has disappeared from SIG’s website as well as dealer offerings. It appears that SIG has refined the brand by incorporating the excellent P320 XFive version into their Legion line.

The Legion series so far have been “purpose built” firearms. Although they are appointed similarly to the “standard models,” they are not all the same guns. The P229, for instance, was built as an EDC handgun. The P320 XFive Legion is built as a competition pistol for those who are interested in shooting the Production or (maybe) Carry Optics divisions.

The XFive Legion slide has the same top lightening cuts and rear and front serrations as the original XFive handgun. The only thing that sets the Legion slide apart from the previous XFive version slide is the SIG Gray finish and the legion mark on the optics plate.

The slide to frame fit is even all the way round, but loose. If you shake the P320 XFive Legion in your hand it rattles almost like an old Government M1911.

The most obvious difference between the regular P320 and the competition-focused XFive model is the frame. The XFive frame is made of a “TXG tungsten infused” polymer with a steel insert. If SIG’s website didn’t say that, I would have thought it was all stainless steel. That’s what it feels like.

SIG SAUER says the tungsten-infused polymer XGrip module allows for the “weight of steel and the flex of polymer.” I wasn’t aware that the flex of a polymer frame was a good thing, but as long as it flexes the same every time, it doesn’t matter.

What does matter is the additional 11.2 oz of weight the XFive frame adds to the gun. I’ve always liked the P320 platform and it’s always been a fast gun. But the XFive frame’s slightly higher grip and increased weight brings that to a whole new level.

This grip, which is also sold separately, brings the otherwise top-heavy P320 into balance. The raw weight of the gun certainly helps reduce muzzle flip, and combined with the slight weight reduction of the slide cuts, the point of balance of the pistol moves down into the shooter’s hands.

Where the P320 always felt a little weird, but shot well, the P320 XFive Legion feels good, and shoots exceptionally well.

And it’s crazy fast and easy to shoot.

There have been few pistols I’ve reviewed that turn money into spent brass as fast as the P320 XFive Legion. Because of the COVID-19 crisis, The Range at Austin changed its shooting hours from 6AM-10AM. Alone in the bays, I loaded up the three supplied magazines and set the target at 7 yards to practice some Mozambique drills.

Ninety seconds later a 50-round box of ammo was empty and I had two palm-sized holes in the target’s chest and head regions. That’s not hyperbole. Including the magazine changes, it took less than two minutes to empty the gun of all three magazines in a reasonably precise manner, and I am not a particularly impressive shooter.

I had to push the target back to make my normal drills challenging. Instead of running the Mozambique at 7 yards, I ran it at 10 and 15. Instead of working standing single hand at 15, I pushed it to 25. I ran though 500 rounds that first morning in no time at all. More would come later.

The P320 XFive Legion comes cut for a slide-mounted optic, and I’m sure SIG would prefer you use their Romeo line pistol optics. That’s not a bad idea, particularly for this gun.

Take a close look at the rear slide plate. It includes the rear sight itself. Once removed, the rear sight goes away. That issue is fixed with the Romeo1 Pro, as the rear sight is integral to the base of the optic. It also fits the gun perfectly.

The irons on the Legion include a fiber optic front sight and adjustable rear sights from Dawson Precision. I like just about everything Dave Dawson makes, and these are no different.

The front sight is thin, but bright, giving the shooter a fast and precise aiming point, but also provides plenty of space around the front sight to maintain visual awareness of the target itself.

The P320 XFive Legion comes with a full length guide rod and 14 pound simple 1991 style recoil spring installed. The XFive Legion also comes with a 12 pound recoil spring in the box.

I did all of my testing without an optic mounted and without pet loads, so I never swapped the recoil spring. If, however, you wanted to run lighter loads and you were running the gun with a mounted optic, the 12 pound recoil spring may be more appropriate.

The detachable flared and funneled magazine well makes it almost a challenge to miss a reload. If the angle of the top of the magazine is anywhere close to correct, just give it a push and the magazine will drive home and lock in place.

Note that if you want to shoot USPSA Production Division, you’ll have to remove the magazine well to be legal.

The magazines’ aluminum base pad is made by the Henning Group and sports a heavily textured bottom with the stylized Legion lamda/private’s rank logo. The base of those 17-round Legion magazine ends flush with the magazine well.

I thought the fact that it doesn’t extend beyond the magazine well might cause some errors in getting it to lock fully in. But since that magazine well is so large and flared, I had no issues at all getting the magazine to lock home every time.

One of the differences between the XFive Legion model of the previous XFive is the trigger. This one has a skeletonized straight shoe with the same odd-looking XFive rake to it, aiming outward from the frame at a roughly 60% angle. It may be odd-looking, but it works great, and has a solid feel to it. The trigger pull on the Legion is advertised as “30 percent lighter.”

I’m not sure which P320 trigger it’s measured against, but it breaks two ounces under 6 lbs, on average. The trigger still has some short creep to it, and some mushiness after the start. It’s a great trigger for the platform, but even at this level, the Legion’s gas pedal can’t be compared to a finely tuned 1911 or Beretta 92.

I used to be hung up on where the reset is on each pistol, but after talking with and observing some of the faster pistol shooters, I’ve stopped paying attention to the reset and completely abandoned the concept of “pinning” the trigger to the rear. Instead, I’m just trying to get my finger back forward as fast as possible and then moving rearward again. The results, especially on a lighting-fast gun like this one, have been an obvious reduction in my split times, without a loss of precision.

Especially for a competition-focused firearm, high round count reliability is a priority. As I mentioned, testing the raw round count reliability of the XFive Legion was not an issue.

The three 17-round magazines that are included with the pistol meant that a full 50-round box was loaded every time. That capacity, combined with the pistol’s simple shootability, made pouring out rounds a breeze.

After those first fast 500 rounds, mostly 115gr Armscor FMJs and some old Cap Arms 115 FMJs, I got into my patented “tub o’ loosies”. This is the plastic tub of rounds I throw together when there’s just one or two left in a box.

These included all types of rounds, frangible, FMJ, XTP, flat point and IWI’s toothy open die cut HP-ish bullet. Grains ranged from 90 to 165. I mixed these rounds into the magazines and shot them all, just over 200 of them. Then I shot another 60 rounds for accuracy.

At no point did I have any issue with the P320 Legion in any way. It never failed to fire, load, or eject. The magazine never failed to snap in place or drop. As usual, I didn’t clean the gun in any way during the review. I did lubricate the rails and the bolt face and the breach with the supplied lubricant. It ran like a champ.

At five inches, the P320 XFive Legion’s barrel length is a bit longer than the stock P320 with a correspondingly longer slide length. That’s a bit more barrel, and a bit longer sight radius, but not much. The precision of the Legion falls right in line with previous models.

The best-shooting round was the IMI 115gr Die Cut bullet, printing 1.9” groups at 25 yards. I’ve shot that round through quite a few guns, and it’s regularly one of the better shooters.

But right on its heels were a host of rounds, including the dirt cheap Armscor 115gr FMJ, the Speer 124gr Gold Dot +P and the Wilson Combat Match 147gr HP. Every one of those rounds were between the 2 and 2.3” mark. All groups were the average of five rounds shot for four-shot strings off a bag at 25 yards. That’s a good, but not exceptional level of precision.

My only disappointment with the XFive Legion, and a real chance to set the Legion model apart from the standard XFive, is that the barrel remains un-threaded. That’s a bummer. The P320 XFive Legion is a fast, cool gun, but nothing’s cooler than quiet.

Other than that, I’m glad SIG chose not to mess with a good thing, and left the P320 XFive pretty much the same as the previous P320 XFive when the created the Legion version.

Ratings (out of five stars):

Style and Appearance * * * * *
I dig the SIG Gray, and the well-placed Legion branding accents are tasteful and well placed.

Customization * * * * *
This is where the entire P320 line shines. Since it’s a serialized chassis gun, you can change everything about it. Slide, frame, sights trigger, barrel, anything you want. The whole point of the Legion version is that THIS is the one you want.

Reliability * * * * *
A wide variety of boring perfection.

Accuracy * * * *
Very good, with a wide variety of rounds, but none scored exceptionally well.

Overall * * * * 1/2
The Legion version of the P320 XFrame makes a good gun even better. I can’t give a full-sized gun that doesn’t break the sub 1″ mark a full five stars, but that’s about all I really have to complain about. If I want a threaded barrel, there are aftermarket options available. The P320 XFive is a good looking, accurate, incredibly easy-to-shoot pistol. I’ve always liked the P320 in general, and really dig the XFive, but this Legion version is the first one that’s hard to give back.

  1. Here come the accusations of TTAG being Sig fan boys. I used to be an accuser. I had to sincerely apologize to Nick at the Texas Firearms Festival after shooting the MPX. I may prefer another brands full size guns, but I will admit that I haven’t had an issue with any Sig I’ve shot.

    Thanks for the review. I may eventually add a 320 to my safe.

  2. Will there be other colors or finishes? Not a fan of the finish on this one. Performance wise it’s hard to beat except maybe a trigger swap at some point.

  3. While reading the article, the price I was “expecting” to see was over $1.1k.
    Glad to see Sig has this priced below that.

  4. I had never fired a Sig until a cousin gave me a lightly used P220. It is the only DA auto I truly like. I am now a Sig believer. While I wouldn’t have use for this particular model, it still an interesting read. When can we expect to see the review of the new Python you mentioned?

    • All I have left to do is some accuracy shooting. But I’ve been working 16 hours a day with this CV19 thing and have had zero time. Maybe next week. I never got my 4.25″ guns in, so the whole review is on the 6″ers.

  5. Good review. I got to run a stage with this pistol at a 3 Gun match in WY last summer; its a beautiful competition pistol that ran like a top. That said, I didn’t care for it, but only for the same reason I don’t like most SIG pistols: the grip is just too girthy for my hands. I struggled controlling the P320 XFive Legion. This is purely personal, and I think they’re solid pistols. However, if you have smaller hands, you may struggle with it. FWIW.

  6. Looks impressive. With that size and weight though why bother with sissy 9mm. A gun that size aught to shoot a real mans caliber like 10mm, .45 super, or .460 Rowland.

  7. One MAJOR con with the X-Five Legion, however, is the fact that it ships with either one (320X5-9-LEGION-R2-1M) or three 17-round magazines, whereas the older X-Five shipped with four 21-round magazines. You would think that the X-Five Legion, being an “upgraded model”, would ship with the larger capacity magazines.

    You would also think the author would mention this? Sig let you keep the gun, did they now?

    • 1. Didn’t even consider it becasue…
      2. The Legion model is LESS expensive than the the previous XFive, not more.
      3. There are no “upgrades” to the XFive, it’s purely cosmetic. I went though that several times.
      4. Think before you post.
      5. Man that would be nice, but I don’t deal with Sig, I deal with TTAG.

      • 1. You should have considered it because…
        2. Although the Legion model is less expensive (Suggested MSRP) than the the previous XFive the street price will likely be similar. Therefore that is a $50 to $200 (Sig prices the 21 round magazines at $49.99 each on their site) difference in value depending upon how one personally values the “lesser” 17 round magazines.
        3. This omission is not about “upgrades” rather it is a “downgrade” that should have been mentioned in a compare and contrast review.
        4. Think before you post…This butt hurt response for being called out for failing to mention a major negative difference shows you now know it should have been included. Capacity is a huge selling point, the Sig 365 again proved that fact, and given the choice, it is likely a sizable majority would choose four 21 round magazines vs three 17 rounders. Your review dropped the ball on this fact, you should have just admitted it.
        5. Man that would be nice, but I don’t deal with Sig, I deal with TTAG. <—That's nice but still doesn't answer whether you are still in possession of the pistol.

        • The goal post has change to if I am still in possession of the gun? Yes, 4 days after having completed the shooting, during the middle of a global pandemic, I have not yet driven it back to the editor. Dumbass.
          And no, I don’t think this is a major negative, and I don’t think you do either. I think you are the same asshole that comes on under one named after the next trying to sound smart nit-picking other people’s work. Try harder.

        • Well you are a real class act.

          In case anyone doesn’t know, the above rant with the name calling, was posted by the author of this review JON WAYNE TAYLOR who is attempting to show off his professionalism in the field of Journalism.

          Apparently JON WAYNE TAYLOR is a fragile soul that can not handle any criticism or he will lash out whining about “nit-picking other people’s work” and begin calling you a dumbass and a asshole.

          It’s nice to know The Truth About Guns hires consummate professionals that can handle themselves in a gentleman manner, respecting the publication they work for, without losing their cool and responding to a critique like a shamed petulant adolescent.

          Class act TAYLOR.

        • Pathetic. You run your mouth, impune my integrity, flail in ignorance, and then play the victim.
          Grow up.

        • Actually the gun was built for USPSA Production and Carry Optics Divisions, the 21 round magazine were not good for either Division because of their length (too long to fit the box for Production and over 141mm for Carry Optics). Many competitors that bought the X5 had to replace their magazines, so on the introduction of this gun they went with the 17 rounders and included the Henning Group Base pads. The 17 round tube is also able to add the extended TTI, Taylor Freelance, Springer Precision or Henning Group pads to increase capacity for Carry Optics and still be at the Divisions restricted length of 141mm. You can swap the spring and follower for a Grams spring and follower and get 23 +1 rounds with that set up.

  8. I bought mine last month. Boy, was I surprised when I went to the range. I especially like the fact that when using my weak hand to shoot, I can still hit the target with definite accuracy. The gun points naturally for me. Shooting this gun is extremely fun. Total cost for mine: $960. Includes taxes and background check fees. You’re gonna need to bring lots of ammo when you take out this gun to the range. I used up close to 500 rounds in one session.

  9. Great review, thanks.
    Have a polymer x5 with the black barrel. Early model had stainless steel. One thing my example was quite different it was tight out of the box. No rattles here. Had to use full power 124s for first 200 rounds then it settled down. About 1500 through it and she’s still snug but functions with target ammo

    • Earlier Legions have a Loaded Chamber Indicator slot milled into the barrel hood. This creates havoc with red-dot optics because escaping gasses fog-up the lens.
      Sig to their credit, has been replacing the barrels at no cost. Guns produced since Jan. 2020 did away with the LCI.
      Another issue is the Ejector. When using 21 round magazines, it’s possible to bend the ejector when slamming the mag in place. Too many bends cause breakage. Unfortunately, replacing the ejector requires replacing the entire Fire Control Unit. The FCU has the gun’s Serial Number stamped on it, so this is a major headache.
      My Legion had numerous failures to return to battery until I switched the recoil spring (included) and the gun has been 100% since, even with my own reloads.

  10. Among others, I own an X-Five Legion and a Springfield Armory Trophy Match 1911.

    The Trophy Match has the best trigger I have ever shot. That is due to the design of the 1911. You can’t find a better trigger than a well tuned 1911. It is also one of the most accurate pistols I have ever shot. I can regularly ping steel at 100 yards.

    I own three P320 pistols including the X-Five and two exchange kits. The modularity of the P320 is a big plus. I can ping steel with the X-Five equally well so accuracy is not a problem. My slide to frame fit is fairly snug so I don’t know what is up with the sample you had. For a striker fired pistol the X-Five trigger is one of the best I have used. It is silky smooth and consistent. It breaks the same every time. True it is not a 1911 trigger but it is an excellent trigger none the less.

    My EDC is now my X-Five. With the SIG Legion kydex holster it tucks under a loose shirt very well. Better than the 1911. With one in the chamber, one 17 round mag locked in, and two 21 round mags in a double mag pouch you have in incredible 60 rounds at your disposal if you wish to carry that much.

    I recently attended a two day training class and shot with 9 other attendees including some LEO. We shot about 600 rounds total. I am not a competition shooter. By the second day they were threatening to move my target back 10 yards just to make it fair. I attribute that to the way the X-Five handles.

    Sig has set the bar with the X-Five at a very reasonable price for what you get in return. Now everyone else has to catch up.

  11. God do I miss Cap Arms ammo. At least the original stuff. The stuff they made at the end was questionable.

  12. I’m surprised at your conclusion about its accuracy. 1.9″ groups at 25 yds is excellent. Unless you were using a Ransom Rest. What sized groups do you normally shoot with your “good guns?”

  13. guys Ive been reading comments..we are all gun lovers and we all have our own opinions and that whats make us individuals..I respect everyone views and experiences…I heard good and bad bout this gun Im still gonna buy it cause love the looks…lets all enjoy shooting and keeping our brothers safe.

  14. Good to see that someone else’s x5 legion rattles as well. I was concerned mine was doing this. But in your experience have you found a solution to the rattling?

    • Take the magazine out and shake it. These magazines are prone to have a loose round rattle. Does not hinder function. It’s not the gun.

  15. I had the x5 and liked it very much then held the Legion and the grip and weight is so much better that I bought the Legion. It shoots outstanding, no jams with all different types of ammo and I’m just an average shot. I love this gun for the range and recommend it highly. It feels great in my hand but it’s big and heavy so I wouldn’t carry it.
