Armscor Rock Island 10777 1911 A1 10mm Auto 8rd Blued Steel Magazine

The Armscor Rock Island 10777 is a factory 8-round detachable magazine designed for Rock Island Armory 1911 A1 pistols chambered in 10mm Auto. Built as the standard OEM replacement for full- and mid-size Rock Island 10mm 1911 platforms, it drops right into the original pistol and feeds reliably round after round.

Constructed from steel with a blued finish, this single-stack magazine matches the classic 1911 A1 profile and keeps the spare-magazine footprint slim and familiar. The detachable design makes range reloads fast, and the 8-round capacity preserves the traditional single-stack feel of the 10mm 1911.

Whether you are topping off a spare magazine carrier or replacing a worn original, the Rock Island 10777 delivers the factory fit and function Rock Island Armory 10mm 1911 A1 owners expect from an OEM part.
