Ruger recently discovered that all Mark IV pistols (including 22/45 models) manufactured prior to June 1, 2017 have the potential to discharge unintentionally if the safety is not utilized correctly. In particular, if the trigger is pulled while the safety lever is midway between the “safe” and “fire” positions (that is, the safety is not fully engaged or fully disengaged), then the pistol may not fire when the trigger is pulled. However, if the trigger is released and the safety lever is then moved from the mid position to the “fire” position, the pistol may fire at that time.

Although only a small percentage of pistols appear to be affected and we are not aware of any injuries, Ruger is firmly committed to safety and would like to retrofit all potentially affected pistols with an updated safety mechanism.

Until your Mark IV pistol has been retrofitted or you verify that it is not subject to the recall, we strongly recommend that you not use your pistol.
