Ruger recently discovered that all Mark IV(TM) pistols (including 22/45(TM) 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. View Safety Bulletin PDF

All Mark IV(TM) pistols produced prior to June 1, 2017 are potentially affected and therefore are being recalled. This includes Mark IV(TM) Target, Hunter, Competition, 22/45(TM), 22/45(TM) Lite and 22/45(TM) Tactical models. These models bear serial numbers beginning with “401” (2017 models) or “WBR” (2016 models).
Firearms NOT subject to the Recall
Newly manufactured Mark IV(TM) pistols will begin with serial number “500.” Thus, if you have a Mark IV(TM) or 22/45(TM) pistol with a serial number beginning with the number “5,” your pistol is not subject to the recall.
