SIG SAUER P365-380 .380 ACP 12-Round Magazine

SIG SAUER P365-380 .380 ACP 12-Round Factory Magazine

Add a genuine factory magazine to a compatible SIG SAUER P365 chambered in .380 ACP. This 12-round magazine is designed for the P365-380 platform and provides additional capacity compared with the pistol’s standard 10-round configuration. Its black steel body and factory follower, spring, and catch geometry make it a practical spare or replacement for range use, training, and routine equipment rotation. This exact magazine is manufacturer part number 8900716.

Made for the P365-380

The P365 family is offered in more than one caliber, so matching the magazine to the pistol is essential. This model is for P365 pistols chambered in .380 ACP. It should not be used in a 9mm P365 simply because the magazine bodies appear similar. Always confirm the caliber marking on the firearm and the ammunition before loading.

The magazine holds 12 rounds of .380 ACP ammunition. Its extended-capacity configuration gives the shooter two additional rounds compared with a 10-round P365-380 magazine and may provide additional gripping surface below the standard compact frame. Actual fit and grip profile depend on the exact P365-380 configuration, so the magazine should be test-fitted while empty before live use.

Factory Construction and Fit

A steel magazine body provides the rigidity needed to maintain feed-lip geometry and move smoothly within the compatible grip module. The black exterior coordinates with the pistol’s standard appearance. Factory-designed follower travel, spring pressure, feed presentation, and magazine-catch placement work together as part of the pistol’s feeding system. Choosing the exact SIG SAUER part number helps avoid confusion with visually similar P365 magazines made for a different caliber or capacity.

Loading and Maintenance

Before loading, verify that the pistol is completely unloaded and that the magazine matches the firearm’s caliber. Insert cartridges one at a time with each round correctly aligned beneath the feed lips. Do not force ammunition into a magazine that is damaged, obstructed, or already at capacity. Follow the current SIG SAUER P365 owner’s manual for loading, unloading, cleaning, and inspection.

Periodically examine the feed lips, follower, spring movement, body, baseplate, and magazine-catch opening for debris, deformation, corrosion, or unusual wear. An empty magazine should insert, lock, release, and drop free normally before it is placed into service. Replace any component that shows damage affecting fit or feeding.

Capacity Restrictions

Magazine laws vary by state and locality, and a 12-round magazine may not be legal for direct shipment, purchase, possession, or use in every jurisdiction.
