The ProMag COL-A3B is a 9mm magazine designed for AR-9 lowers with Colt pattern magazine wells. This 32 round magazine is an affordable option to fully finish your pistol caliber carbine build. This Colt pattern magazine is made from a durable polymer with an internal steel lining for increased durability and reliability. The internal steel lining extends up to the feed lips to ensure proper function for many years and it also helps to keep the magazine securely locked into the magazine well. This 9mm Colt magazine utilizes an anti-tilt follower and hardened chrome silicon follower spring that will retain proper tension, even when fully loaded for long periods of time. The polymer body features a stippled texture that makes it easy to grab for fast mag changes whether you are wearing gloves or in a rainy environment. Grab a couple ProMag Colt 9mm carbine magazines, load up 32 rounds of your favorite range ammo, and you’re ready to head to the range.

Good but didn't work for my setup.

The mag looks good, feels good, fully loaded it swelled up a little but making it difficult to insert. I was using bayou bullet reloads and I was getting ftf's every 3 round or so, jamming it up into the receiver. I found that the feed angle is level with the barrel and not angled up like my other mags that function flawlessly. I am also using a colt 604 upper receiver, cmmg lower, and another brand's 9mm barrel. Other mags run great, this one just has issues for me.
