Buds stock is not affected by this recall. I have confirmed this with Julia via live chat.

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). - Firearms NOT subject to the Recall
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. You will need to contact Buds Customer Service 859-368-0371 M-F 9am-9pm to inquire about serial number range.
