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).

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.
