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.
