Sig Sauer MAG-MOD-F-43-18 P320/P250 .40 S&W/.357 Sig 18-Rd Blued Steel Magazine

The Sig Sauer MAG-MOD-F-43-18 is a factory-original 18-round detachable blued steel magazine built for the Sig Sauer P320 and P250 full-size pistol families. This OEM magazine is designed and tested specifically for SIG SAUER pistol platforms, and it feeds both .40 S&W and .357 Sig loads through the same body, giving shooters a single spare that covers either caliber in their full-size Sig pistol.

Constructed of metal with a durable blued finish, this magazine drops into any standard P320 Full Size or P250 Full Size pistol chambered in .40 S&W or .357 Sig. The 18-round capacity fills the standard full-size grip frame, and the unit installs without modification using the factory magazine release.

Whether you are stocking a spare for a duty rotation, replacing a worn magazine body, or topping off range gear, the SIG MAG-MOD-F-43-18 is the correct factory magazine for your full-size P320 or P250 in .40 S&W / .357 Sig.
