Mag Rock Isand 1911 A1 10mm 8rd

The Rock Island Armory 1911 A1 10mm 8-round magazine is a factory-specification replacement designed for full-size and mid-size 1911 platforms chambered in 10mm. Built to Armscor manufacturing standards using the same materials and tolerances as original equipment magazines, this steel magazine delivers the reliability required for duty, competition, and training applications where magazine dependability is non-negotiable.

The magazine features a steel body paired with a polymer base plate, a proven combination that balances durability with ease of disassembly for cleaning and maintenance. The 8-round capacity reflects 10mm's higher recoil impulse compared to 9mm and .45 ACP, allowing for proper powder charge and case capacity without compromising structural integrity or feed reliability. The tight engineering tolerances ensure consistent chambering and extraction across repeated duty cycles.

This magazine serves defensive shooters, range competitors, and law enforcement who rely on the 1911 platform in 10mm for its terminal performance and controllability. Whether building a complete duty rig or maintaining backup magazine inventory, the Rock Island Armory mag meets the exacting standards established by the 1911's legacy. Operators running full-size steel-frame 1911s benefit from the predictable ergonomics and proven feed geometry that have defined the platform for over a century.
