The CMC Products Range Pro 1911.45 ACP 8-Round Black Oxide Magazine is an American-made aftermarket centerfire pistol magazine constructed around a tough, precision-machined stainless steel body with a black oxide finish for lasting field service in virtually any environment. It is built for long-lasting corrosion and abrasion resistance. It is the best option for carry, competition, and general range use thanks to an updated, removable polymer floor plate that provides snag-free performance and an increased grip. For more dependable feeding, the stainless steel spring and steel anti-tilt follower avoid binding, and numbered witness holes provide quick, visual round counts. Additionally, this handgun magazine is naturally resistant to abrasion and corrosion for increased strength and long-lasting endurance without adding weight to you.
