Sig Sauer Magazine P320/P250/M17/M18 Full-Size 21 Rounds Cal. 9mm – Coyote

Sig Sauer Magazine P320/P250/M17/M18 Full-Size 21 Rounds Cal. 9mm – Coyote

The Sig Sauer MAG-MOD-F-9-21-COY magazine is an original extended double-stack 21-round magazine chambered in 9mm Luger, manufactured to SIG SAUER specifications for Full-Size pistol platforms, including the P320, P250, M17, and M18. The Coyote finish matches the corresponding color variants of SIG SAUER pistols, widely used in tactical and military contexts.

The body is made of steel for durability and reliability over time, while the polymer baseplate makes it easier to grip and insert into the pistol's magazine well. Compared to the standard 17-round magazine, this extended 21-round version offers greater firing capacity while retaining the size and feed reliability typical of the P320/P250 platform.
