The ProMag COL-A3B is a 32-round 9mm Luger magazine purpose-built for AR-15 platforms chambered in 9mm, including Colt Carbine and SMG configurations. If you're running a 9mm AR or PCC (pistol-caliber carbine), having reliable spare mags is non-negotiable—and this polymer-construction mag offers a lightweight, cost-effective way to keep ammunition on hand at the range or in the field without the weight penalty of steel magazines.
Built from DuPont Zytel polymer with a steel-lined body, the COL-A3B delivers the durability you need for regular use. The injection-molded follower and chrome-silicone wire spring are engineered to handle repeated loading cycles and feed reliably through your 9mm AR platform. The black finish blends with modern tactical setups and resists scuffs typical of range duty and transport.
This is a detachable, quick-change design—pop it out, swap in a fresh magazine, and keep running. Made in the USA, the ProMag COL-A3B is the kind of straightforward, no-nonsense accessory that works well when you need it and doesn't demand a premium price. Whether you're stocking up for a match, practicing at the range, or building redundancy into your 9mm carbine kit, this 32-round magazine is a practical addition to any 9mm AR lineup.

DuPont Zytel polymer magazines are lighter than steel, reducing overall load-out weight—especially valuable when carrying multiple spares.

Both materials are reliable; polymer is simply preferred by shooters prioritizing mobility and comfort.
