The SIG Sauer P320/P250 9mm Magazine (brand part no. 8901372) is a genuine factory-pattern 10-round magazine built for full-size P320 and P250 pistols, giving you a durable steel-body magazine backed by a lighter aluminum baseplate. Sig Sauer finishes the magazine in black and adds side witness holes so you can verify your round count at a glance without dropping the mag.
