Ruger announced that it is recalling all Mark IV pistols (including 22/45 models) manufactured prior to June 1, 2017. Ruger recently discovered that the pistols 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), 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 Mark IV pistols appear to be affected and the Company is 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. As a responsible manufacturer, Ruger wants to make its customers aware of this FREE safety upgrade. All Mark IV pistols with serial numbers beginning with “401” (2017 models) or “WBR” (2016 models) are subject to the recall. Mark IV owners should visit the Mark IV Recall website at Ruger.com/MarkIVRecall to look up the serial number of their Mark IV and verify if it is subject to the recall, sign up for the recall, and obtain additional information.
