Ruger has issued a safety bulletin for their SR22 pistol. The issue occurs when the left and right sides of the frame inserts are not properly attached to each other, causing the firing pin blocker and hammer block to move separately of each other.
If this happens, the pistol can sometimes have a “slack” single action trigger with the potential to discharge when decocked over a live chamber.
Ruger has stated in their bulletin that only a small number of guns appear to be affected by this gun recall. They would, however, like to inspect all pistols that have ever shown this “slack” trigger in single action, or have discharged upon decocking.
Ruger says that if you have ever experienced either issue, that you should stop using the pistol immediately and return it to the company for a retrofit. Furthermore, Ruger says:
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.
Nothing needs to be done if you haven’t experienced either of the above scenarios, or if it doesn’t fall within the stated serial numbers.
