SIG SAUER P250/P320 Compact 10-Round .40/.357 SIG Magazine

The SIG SAUER P250/P320 Compact 10-round magazine is a factory magazine for compatible compact pistols chambered in .40 S&W or .357 SIG. This exact configuration carries UPC 798681505111 and is cataloged by SIG SAUER as part number MAG-MOD-C-43-10; the product record stores the same identifier in compact distributor format as MAGMODC4310.

Made for compact P250 and P320 pistols

SIG SAUER lists this magazine for compact-size P250 and P320 models. The compact magazine body is designed around the intended grip-module length, magazine-catch location, feed angle, and slide-lock interface. Buyers should verify the pistol model, compact grip size, and chambering before ordering, because full-size and subcompact magazines use different physical configurations.

Compatible with .40 S&W and .357 SIG

This factory magazine is specified for both .40 S&W and .357 SIG. The shared magazine format reflects the cartridge dimensions used by compatible P250 and P320 pistols in these chamberings. Its detachable double-stack design holds 10 rounds and uses a steel body, factory follower, spring, feed lips, and baseplate as a complete assembly.

Useful as a replacement or range spare

A spare factory magazine can reduce interruptions during a range session and provide a direct replacement for a worn or damaged unit. Marking magazines individually with a removable identifier can help isolate a particular magazine if a feeding or slide-lock issue appears. Inspect the body and feed lips for deformation, make sure the baseplate is secure, and confirm that the follower moves smoothly before use.
