The SIG SAUER P365 9mm 25-round magazine is a factory OEM high-capacity spare mag built for shooters who want maximum round count while staying with genuine SIG fit, finish, and reliability.

This exact magazine, SKU 2700939-01P-R, is designed for the P365 family in 9mm and fits all 9mm P365 models, including the P365 Standard, P365X, P365-XL, P365-XMACRO, P365-AXG LEGION, and P365-FUSE. It is an excellent choice for training, range use, staged reloads, or simply keeping additional factory magazines ready to go.

Constructed with a steel magazine body, polymer baseplate, and black oxide finish, this factory mag is built to SIG SAUER specifications. It also features rear witness holes for quick round-count confirmation and an orange follower for fast empty-mag identification.

The baseplate is designed to seat at the bottom of P365-XMACRO, P365-AXG LEGION, and P365-FUSE size grip modules. When used in P365 Standard, P365X, and P365-XL size grip modules, there will be a visible gap at the base of the magazine.
