Ruger SR22 Product Safety Bulletin

From Ruger . . .

In rare instances, if the left and right frame inserts of Ruger SR22 pistols are not properly secured together, the firing pin blocker lifter and hammer block can move independently of each other, potentially rendering them ineffective. If this situation occurs, the pistol will intermittently exhibit a “slack” single-action trigger and has the potential to discharge if decocked over a live round. NOTE: A “slack” single-action trigger occurs if, while operating the pistol in single-action mode with a magazine inserted, the slide forward, and the manual safety disengaged, a trigger pull does not encounter resistance and the hammer does not fall.

Although only a very small number of pistols appear to be affected, Ruger is committed to safety and would like to examine all SR22 pistols that have ever exhibited a slack single-action trigger or discharged upon decocking. If you experienced either condition, please immediately stop using your SR22 and return it to Ruger for this Safety Retrofit. If you have not experienced either condition, your pistol is not subject to this Safety Bulletin unless one or both of these conditions occur in the future.

Products Subject to this Safety Bulletin and Who Should Sign Up

Any SR22 with serial number 369-40078 or lower (including those with a “SS” serial number prefix) is subject to this Safety Bulletin, IF it has either: (1) exhibited (or exhibits in the future) a slack single-action trigger; or (2) discharged upon decocking. If you have ever experienced either of these conditions with your SR22 pistol, you should stop using your pistol and sign up for the Safety Retrofit.

Note: A slack trigger will occur during normal operation if: 1) the magazine is removed; OR 2) the slide is locked to the rear; OR 3) the manual safety is engaged. These are all normal operating conditions.

This Safety Bulletin applies only if a slack single-action trigger is experienced with the magazine inserted, the slide forward, and the manual safety disengaged.

If You Experience a Slack Single-Action Trigger While Shooting, Take the Following Steps Immediately:

  • Keep the pistol pointed in a safe direction at all times.
  • Do not attempt to remedy the matter by engaging the safety lever.
  • Remove the magazine from the pistol.
  • Retract the slide and lock it back.
  • Visually and physically verify that the chamber of the pistol is empty.
  • With the pistol pointed in a safe direction, the chamber empty, and the magazine removed, carefully close the slide and engage the safety lever to decock the pistol.
  • Do not use the pistol until it has been examined by Ruger. Store it safely until it can be returned to the factory.
  • Sign up for the Retrofit on this page, or by phone at 336-949-5200 to arrange to return the pistol for evaluation and repair, if necessary.


Always treat every firearm as though it is loaded and always keep the muzzle pointed in a safe direction. Never rely upon any safety or mechanical device to justify unsafe or careless firearm handling.

  1. Ten years on the market and they still do not have the bugs worked out of it yet??? Platicky equals junk.

    • Fake dacian. Notice the poor spelling and obvious lack of education.

      My bad. That’s the real dacian.

  2. If you ask the usual suspects on ar15.comedy about Ruger Trigger Slack chances are good the reply would be, You got OCD dude, slack is normal.

  3. In other words, “it’s not a problem until it’s a problem.”

    This does not give me warm fuzzies.

  4. Does this mean that when the decocker is engaged it doesn’t physically block the hammer from hitting the firing pin? If so I don’t think I’ve ever seen a system that didn’t have such a dead-basic safety feature.

  5. I have a few Ruger .22 lr pistols. A Standard Model. A couple of 5.5″ bull barrels. A MK I and MK II. Blued and stainless respectively. They’re steel. They’re a bit heavy. They’re reliable. They’re accurate. They seldom break. (Only once. A recoil spring recoil guide rod. $7.00. Brownell’s.) They’re easy to fix if they do. What was I saying? Oh, yeah! They’re FUDD guns! You young guys that piss plastic do not want one! Ever! Call me if you see one at a reasonable price. MK II and earlier please. Also, any quality .22 rifle. You want a MSR! Got enough non FUDD rifles to arm a rifle squad. They’ve begun to bore me. I’ll never get rid of any of them. I’m more likely to buy another one. All my life, I’ve won matches, a few trophies, and what I’m most proud of, a couple of shots in the field that no one saw but me. Learned riflery with a .22. Began handgun shooting with an older friend’s .22 revolver. As long as I bought the ammo. Ignore .22 lr at your peril.

  6. I should express that I like this article so a ton and moreover using it in regular. I believe you would continue sharing better than average articles here.
