SIG SAUER P320/P250 Full-Size .45 ACP 10-Round Magazine

This factory SIG SAUER magazine is the full-size, 10-round .45 ACP configuration identified by manufacturer part number MAG-MOD-F-45-10 and UPC 798681505173. SIG SAUER lists it for compatible P320 and P250 pistols, including the P320 Full/Carry application.

OEM Design and Materials

The magazine uses a steel body with a black finish, a polymer follower, and a polymer baseplate. Its double-stack layout provides a 10-round capacity while retaining the factory geometry intended for the compatible pistol platform. Side witness holes give a convenient visual reference during loading and inspection.

Fit and Selection

This is a full-size magazine for compatible .45 ACP P320 and P250 configurations. Magazine compatibility depends on caliber, grip-module length, and magwell or baseplate clearance, so compare the firearm and grip configuration with the factory part number before ordering. It is not a substitute for 9mm, .40 S&W, or .357 SIG magazines, and it should not be selected solely because another magazine from the same pistol family looks similar.

Maintenance and Use

A factory magazine is a practical choice for range rotation, training, or replacement use. Keep the body and follower free of grit and excess lubricant, and periodically inspect the feed lips, spring tension, follower travel, and baseplate retention. Testing each magazine with the specific pistol and ammunition used helps confirm reliable function before the magazine is placed into regular service.

This listing includes one magazine only. Ammunition and firearm are not included. Magazine-capacity laws and shipping restrictions vary by location; confirm eligibility before purchase.
