Rock Island 10777 1911Blued Detachable 8rd for 10mm Auto Rock Island 1911 A1

If you're running a Rock Island 1911 A1 in 10mm, having reliable factory magazines on hand isn't optional—it's essential. This 8-round detachable magazine for Rock Island's full and mid-sized 1911 platforms is built to the same specifications and tolerances as the OEM mags that shipped with your pistol, meaning it'll drop in and function without the break-in period or fitment guesswork that sometimes comes with aftermarket alternatives. Steel construction paired with a polymer base plate keeps things durable while managing recoil impulse, and at 8 rounds per mag, you're looking at realistic capacity for a hard-hitting cartridge like 10mm.

Whether you're prepping for a range session, building redundancy in your carry rotation, or simply replacing wear-and-tear magazines, having spares manufactured to factory spec removes variables from the equation. Armscor produces these to their own rigorous standards, so you're getting the same attention to detail that goes into Rock Island Armory's firearms themselves.

Ten-millimeter shooters know the cartridge demands respect—and respect starts with magazines that feed reliably, every time. This isn't a budget workaround; it's a straightforward factory replacement that does exactly what it should.
