The SIG SAUER P365 9mm 25-round magazine is a factory extended-capacity option for training, range sessions and other applications where additional ammunition capacity is useful. Designed for the 9mm P365 family, this double-stack magazine uses a steel body with a black oxide finish and a black polymer baseplate. Its 25-round capacity reduces the number of reloads required during extended practice sessions while retaining factory configuration and compatibility across the broad P365 lineup. Rear witness holes provide a convenient way to check loaded capacity, and the high-visibility orange follower is easy to see when the magazine is empty. The installed baseplate is shaped to seat against longer P365 grip modules, including the P365-XMACRO, P365-AXG LEGION, P365-FUSE and P365-DH3 configurations. It is also compatible with standard P365, P365X, P365-XL, P365-XL COMP, P365-XMACRO COMP and P365-FLUX models chambered in 9mm Luger. When installed in shorter P365 Standard, P365X or P365-XL grip modules, the magazine remains functional, but a visible gap will remain between the grip and baseplate because the baseplate is dimensioned for the longer grip profile. This distinction is helpful for owners selecting a magazine for more than one P365 configuration. The extended body and substantial capacity make this magazine particularly practical as a range magazine or spare magazine for compatible platforms. As an original SIG SAUER accessory, it is manufactured to the company's specifications for the P365 system. Magazine stamping and finish shade may vary slightly because SIG SAUER sources magazines from multiple manufacturers, but the required configuration remains the same. Before loading or using this magazine, confirm that the pistol is a compatible 9mm P365 model and that its 25-round capacity is permitted under applicable state and local regulations.Specifications and Features: 25-round capacity for 9mm Luger Compatible with all 9mm P365 models Black oxide-finished steel magazine body Black polymer baseplate Double-stack configuration Rear witness holes show loaded capacity High-visibility orange follower Baseplate sized for XMACRO, AXG LEGION, FUSE and DH3 grips A gap remains when used with Standard, X or XL grips Color: Black Brand: SIG SAUER Series: P365 Product Type: Pistol Magazine Manufacturer Part Number: 8901941 UPC: 798681729746
