The ProMag GLKA11 is a 13-round .40 S&W magazine built to feed your Glock 23 or 27 reliably at the range or in the field. If you shoot one of those compact duty or carry pistols and want an extra mag without the premium price tag, this detachable magazine gives you genuine capacity and rock-solid construction without the corporate logo markup. ProMag engineered this one to run, not to sit pretty in a display case.
The magazine body is molded from a proprietary DuPont Zytel-based polymer—the same tough thermoplastic that handles temperature swings and impact without cracking or warping. Inside, you'll find a full-length steel insert that's stamped and welded the same way factory mags are made, so the guts are where the reliability actually lives. The follower is injection molded to spec, and the spring is wound from heat-treated chrome silicon wire, so feeding stays consistent through hundreds of cycles.
Made in the USA, this is a no-frills alternative magazine that respects your budget while delivering the dependability you need. Whether you're stocking spares for training, competition, or everyday carry, the GLKA11 fills the gap between bare-bones pricing and overpriced OEM equivalents. Drop it in your Glock 23 or 27, load it up, and get to work.
