SIG SAUER P250/P320 Subcompact 9mm 12-Round Magazine

SIG SAUER P250/P320 Subcompact 9mm 12-Round Magazine

The SIG SAUER P250/P320 Subcompact 9mm 12-round magazine is a factory-specification replacement or spare magazine for compatible SIG P250 and P320 Subcompact pistols chambered in 9mm Luger. Identified by manufacturer part number MAG-MOD-SC-9-12 and UPC 798681505050, this model provides a 12-round capacity in a compact, double-stack configuration. It is intended for shooters who want an additional magazine that follows SIG SAUER’s stated materials, dimensions, and performance specifications for the supported pistol platforms.

Factory-Specified Construction

SIG SAUER specifies a durable steel magazine body with a zinc-phosphate finish. The dark, low-glare treatment helps protect the body during routine carry, training, and storage, while the polymer baseplate provides a practical gripping surface for handling and removal. Side witness holes allow a quick visual check of the approximate ammunition count. The double-stack body provides the listed 12-round capacity while maintaining the profile required by compatible Subcompact grip modules.

Compatibility and Fit

This magazine is listed by SIG SAUER for P250 and P320 pistols chambered in 9mm, with Subcompact and Compact X pistol sizes shown in the manufacturer’s specifications. Because P320 grip modules, frame sizes, and magazine generations can differ, confirm the pistol model, caliber, grip-module size, and required baseplate geometry before ordering. It should not be selected solely because a pistol is part of the broader P320 family.

For the most reliable fit, compare the existing magazine’s manufacturer part number and baseplate shape with this model. Capacity restrictions vary by jurisdiction, so buyers should also confirm that a 12-round magazine is lawful where it will be purchased, possessed, and used.

Inspection and Maintenance

Before use, verify that the magazine seats securely and releases normally with the firearm unloaded and pointed in a safe direction. Periodically inspect the feed lips, body, witness holes, follower, and baseplate for damage, deformation, or debris. Keep the interior clean and dry; excessive lubricant can attract fouling and interfere with dependable feeding. Follow the firearm and magazine manufacturer’s instructions for disassembly, cleaning, loading, and safe handling.

Manufacturer Appearance Note

SIG SAUER notes that magazines may be sourced from more than one manufacturer while still being produced to SIG specifications. Minor differences in stamping or finish color may therefore occur without changing the magazine’s intended function or compatibility. Confirm the exact part number and application rather than relying only on cosmetic details.
