Sig Sauer MAGMODC4310 P320/P250 Compact 40 S&W / 357 Sig 10-Rd Blued Steel Magazine

The Sig Sauer MAGMODC4310 is a factory OEM detachable box magazine purpose-built for the P320 Compact and P250 Compact pistols. Machined from blued steel for long service life and reliable feeding, this 10-round magazine is rated for both .40 S&W and .357 Sig chamberings, giving Compact owners a single spare that covers two calibers in the same grip frame.

Designed as a true Sig Sauer factory part, the body, follower, and basepad are built to factory tolerances and drop right into the Compact grip without fitting. The blued steel construction resists wear from repeated loading cycles, while the compact-specific geometry means it will not seat in full-size P320 or P250 frames, ensuring you always reach for the correct magazine for your carry or duty pistol.

Whether you run a P320 Compact as a duty gun, a P250 Compact as a backup, or simply stock the range bag with reliable 10-round spares, the MAGMODC4310 delivers the same fit, finish, and reliability Sig Sauer builds into every pistol that leaves the factory.
