From the Ruger announcement:
Ruger has issued a safety bulletin on the SR22 pistol:
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.
