The SIG SAUER P365/X/XL/XMACRO 17-round 9mm magazine is a factory OEM spare mag built for shooters who want higher capacity with broad compatibility across the P365 family.

This exact magazine, SKU 8900804, comes configured for the P365-XMACRO but also fits all P365 9mm models, including the P365, P365X, P365-XL, P365-XMACRO, P365-XMACRO COMP, P365-AXG, and P365-FUSE. It is an excellent choice for carry rotation, range use, training, or simply keeping additional factory mags loaded and ready.

Constructed with a steel magazine body, polymer baseplate, and black oxide finish, this magazine is built to SIG SAUER factory specifications. Rear witness holes allow quick visual confirmation of loaded round count, while the orange follower makes it easier to identify an empty magazine at a glance.

SIG also includes two additional interchangeable floor plates to accommodate grip length differences on the P365, P365X, and P365-XL, giving this magazine more flexibility than a typical model-specific spare mag.
