The brand New S&W M&P 12 Bullpup shotgun was just issued a safety recall by the company for two reports of a cracked barrel. A cracked barrel is dangerous for hopefully obvious reasons.
This safety recall affects all shotguns manufactured before October 15th 2021. Smith & Wesson has asked all shotguns be returned to them for inspection, and if your shotgun has a barrel that is affected it will be replaced at no cost to you.
If you have one of these shotguns, please contact S&W for a pre-paid return so they can start the process of inspecting your firearm and return it to you quickly.
