ProMag GLKA14 StandardBlack Detachable 13rd for 45 ACP Glock 21/30

The ProMag GLKA14 is a 13-round .45 ACP magazine built for Glock 21 and Glock 30 pistols. If you run either of those guns—whether for duty carry, home defense, or the range—this magazine gives you a straightforward capacity boost in a standard black finish. ProMag backs these with a lifetime guarantee against manufacturer defects, and they're made in the USA.

What matters most in a magazine is reliability, and ProMag's manufacturing process reflects that priority. Each magazine uses precision-wound springs made from heat-treated chrome silicon wire, a step that resists fatigue and maintains tension over thousands of cycles. The assembly is checked and double-checked at every stage, which is the kind of attention you want in a component that directly affects how your gun runs.

The durable polymer construction keeps weight down and corrosion out of the equation, making these mags at home in any environment—whether you're shooting indoors, training hard, or carrying in adverse conditions. At 13 rounds, this is a substantial capacity upgrade for either the compact Glock 30 or the full-size 21, and the standard black finish matches most tactical setups without fuss.
