SIG SAUER P365 9mm 10-Round Magazine with Finger Extension

SIG SAUER P365 9mm 10-Round Magazine with Finger Extension

This factory SIG SAUER magazine is built for the original P365 micro-compact pistol chambered in 9mm. It combines a ten-round capacity with a polymer finger-extension baseplate, giving the shooter additional support below the compact grip while retaining the standard P365’s short overall profile. It is a practical replacement for an original magazine or an additional magazine for training and range use.

The magazine uses a steel body with a black oxide finish, a polymer follower, and side witness holes for checking the approximate round count. Its removable polymer baseplate incorporates the finger extension rather than increasing ammunition capacity. The extension can improve purchase for shooters whose little finger would otherwise sit below the standard P365 grip, while preserving the ten-round configuration.

Key Features

• Factory SIG SAUER magazine: Manufactured to SIG SAUER specifications for the standard P365.
• Ten-round capacity: Holds ten rounds of 9mm Luger ammunition.
• Finger-extension baseplate: Adds gripping surface below the compact P365 frame.
• Steel body: Black oxide-finished steel construction with a polymer follower and baseplate.
• Side witness holes: Provide a convenient reference for the loaded round count.
• Detachable design: Suitable as a direct replacement or spare magazine.

Compatibility

This magazine is designed for the original standard-size P365 micro-compact grip module. SIG SAUER specifically states that it is not compatible with P365X, P365-XL, XMACRO, AXG, or FUSE models. Those variants use longer grip modules and different flush-fit magazine dimensions. Confirm the firearm model and compare the existing magazine before ordering.

For dependable operation, inspect the feed lips, follower, spring tension, and baseplate before use. Keep the magazine interior free of dirt, lint, and excess lubricant, and follow SIG SAUER instructions for cleaning and disassembly. Function-test the magazine with the specific pistol and intended ammunition before relying on it.
