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. HOW TO DETERMINE IF YOUR PISTOL NEEDS THE RETROFIT All Mark IV™ pistols produced prior to June 1, 2017 are potentially affected and therefore are being recalled. This includes Mark IV™ Target, Hunter, Competition, 22/45™, 22/45™ Lite and 22/45™ Tactical models. These models bear serial numbers beginning with “401” (2017 models) or “WBR” (2016 models). Mark I, Mark II™ and Mark III™ Pistols are NOT affected. Newly manufactured Mark IV™ pistols will begin with serial number “500.” Thus, if you have a Mark IV™ or 22/45™ pistol with a serial number beginning with the number “5,” your pistol is not subject to the recall. Mark IV™ and 22/45™ pistols retrofitted with the updated safety mechanism are easily identified by the letter “S” in the white safety dot that is visible when the safety is engaged. Visit the Mark IV™ Recall website at Ruger.com/MarkIVRecall to look up your serial number and verify if it is subject to the recall. Please have the unloaded pistol available when you visit the website and obtain the serial number directly from the pistol. IF YOUR PISTOL IS AFFECTED STEP 1: Follow the instructions at the Mark IV™ Recall Website and sign up for the recall. You will be asked to provide your name, address, telephone number, an e-mail address, and the serial number of your pistol. STEP 2: You will be added to a list to have the retrofit installed on a first-come, first-served basis. In the next few weeks, you will receive a prepaid USPS box with a shipping label and detailed packaging and shipping instructions. Simply follow the instructions in your instruction manual to separate the barrel/ receiver assembly and return the grip frame assembly to us in accordance with the shipping instructions. STEP 3: We will install the updated safety mechanism, and return your grip frame assembly to you, all FREE of charge. Individual consumers will receive a FREE magazine (a $29.95 value) as a “thank you” for their patience and cooperation. (Customers in states with magazine shipping restrictions will receive a ShopRuger gift certificate in lieu of a magazine.) We will make every effort to return your pistol within one week of the day we receive it.
