Product Description
The Sig Sauer P365-XMACRO 17-Round 9mm Factory Magazine in Black (SKU: 8900804 / UPC: 798681660254) is an authentic OEM steel replacement magazine engineered specifically for the high-capacity P365-XMACRO series while offering backwards compatibility across the entire P365 family of 9mm micro-compact handguns. Designed to deliver full-size 17+1 round firepower in a concealable footprint, this genuine factory magazine delivers uncompromised feeding reliability and exact lockup geometry.
Constructed from durable, heat-treated steel with a slick, friction-reducing black finish, the 8900804 magazine features high-visibility rear witness holes for rapid round counts. Inside, a high-tensile steel spring and high-visibility, anti-tilt follower keep 9mm Parabellum cartridges properly presented for uninterrupted feeding under rapid cycling. The kit comes complete with three interchangeable floorplates, allowing the magazine to fit flush in XMACRO frames or seat properly in standard P365, P365X, and P365XL grip modules.
Whether stocking up on extra magazines for high-volume range training, concealed carry reserves, or competitive shooting, the Sig Sauer 8900804 magazine delivers factory-certified durability and drop-free reload performance.
