Rock Island Armory 1911 A2 10mm / .40 S&W 16-Round Factory Steel Magazine - OEMP164015B - UPC: 812285021270
Product Description
The Rock Island Armory OEMP164015B is a factory OEM 16-round double-stack magazine designed for 1911 A2 wide-body pistols chambered in 10mm Auto and .40 S&W. Built specifically to handle the high energy and harsh recoil impulse of 10mm loads, this magazine features a heavy-gauge carbon steel body with a corrosion-resistant blued finish, delivering durable long-term performance and drop-free execution during rapid reload cycles.
Engineered for high-capacity 1911 double-stack frames, the magazine housing transitions into a precise double-to-single feed taper at the top, facilitating smooth feeding into the chamber. Internally, a high-tensile steel spring works alongside an anti-tilt follower to ensure consistent cartridge presentation and positive slide-stop engagement on empty chamber lockouts.
Equipped with a fitted high-impact polymer baseplate, the OEMP164015B protects the base components from shock deformation when dropped on concrete or gravel range floors. Stamped witness holes along the steel housing allow shooters to quickly check round counts while staging magazines for range drills, competition courses, or field duty.

Maintenance & Staging Steps:
1. Depress the floorplate retaining pin through the bottom hole of the polymer basepad using a punch tool.
2. Slide the baseplate forward off the retaining tabs while firmly securing the internal lockplate and spring.
3. Wipe down the interior body walls using a dry nylon brush to remove unburnt powder residue; avoid excessive oil inside the tube to prevent attracting dirt and carbon.
