SIG Sauer® P365 / P365X / P365-XL / P365-XMACRO / P365 AXG LEGION / P365-FUSE Magazine, 21-Round, 9mm

The original SIG Sauer 21-round magazine is designed for the P365 family of pistols chambered in 9mm. Compatible with the entire P365 platform, including XMACRO, AXG LEGION, FUSE, DH3, and FLUX variants, it provides increased ammunition capacity for training, competition, duty use, or everyday carry as a spare magazine.

Compatible with the Entire P365 Platform

This magazine is compatible with all 9mm SIG Sauer P365-series pistols, including the P365, P365X, P365-XL, XMACRO, AXG LEGION, FUSE, DH3, and FLUX configurations. The magazine baseplate is optimized for full-size grip modules such as the XMACRO, AXG LEGION, FUSE, and DH3. When used in standard P365, P365X, or P365-XL models, a visible gap between the magazine and grip module may remain, but reliability and function are unaffected.

Designed for Practical Use

Witness holes on the rear of the magazine body allow quick verification of ammunition count. An orange follower provides clear visual confirmation of an empty magazine, while the black baseplate complements the appearance of the P365 series.

Factory-Original SIG Sauer Magazine

Manufactured to SIG Sauer specifications, this magazine is designed to provide reliable feeding and consistent performance across the P365 platform. Its 21-round capacity makes it suitable for range use, competition shooting, and as a high-capacity backup magazine.

Note: Product images may differ slightly from the delivered item. Original SIG Sauer magazines are manufactured at multiple production facilities and undergo centralized quality control. Minor variations in markings, finish, or color may occur depending on the production batch.
