The Sig Sauer P365 9mm 21-Round Magazine is a factory-designed, high-capacity magazine built for superior reliability and seamless compatibility across the entire P365 lineup. This steel double-stack magazine features a black oxide finish for enhanced durability, ensuring smooth function in your P365 pistol.
Designed as the standard magazine for the P365-FUSE model, it is also fully compatible with all 9mm P365 models, including the Standard, X, XL, XMACRO, and AXG-LEGION variants. This magazine features rear witness holes to confirm loaded capacity, an orange follower for quick visual confirmation when empty, and a black polymer baseplate. The baseplate is designed to seat flush with P365-XMACRO (AXG LEGION & FUSE) size grip modules, but when inserted in the P365 Standard, P365X, or P365-XL, a slight gap will be present.
