This is a factory extended .40 S&W/.357 Sig 12-round magazine for Sig P224 pistols.
Refined through decades of innovation and successful use by law enforcement and military professionals (including the US Navy Seals), the Sig P224 is a subcompact powerhouse.
These factory extended magazines will give you a full 12 rounds of hard-hitting .40 S&W/.357 Sig, along with a grip extension that makes them ideal for target practice and home defense. Featuring a blued stainless steel construction and rugged internals, each Sig magazine is designed to help make the most out of your P224 pistol.
Remember to rotate loaded magazines (especially extended magazines) every 3-6 months in order to maximize their effective lifespan.
