The ProMag GLKA11 is a 13-round magazine engineered for Glock 23 and Glock 27 pistols chambered in .40 S&W. The magazine body is constructed from DuPont Zytel-based polymer with a full-length internal steel insert that prevents feed lip distortion and adds structural rigidity. These are manufactured in the USA and use an injection-molded follower paired with a heat-treated chrome-silicon spring designed to resist taking a set even after extended storage.
With numbered witness holes along the side, you can quickly verify your round count at a glance. The polymer construction keeps things lightweight while the steel reinforcement maintains durability through regular use. The Glock 23 pairs well with this magazine since it handles 13 rounds comfortably, and the Glock 27 can accept it for increased capacity beyond its standard 9-round factory mag.
ProMag backs every magazine with a lifetime guarantee against manufacturer defects. This is a practical choice for adding to your range rotation or building a spare magazine supply. Like any aftermarket magazine, function can vary depending on your specific firearm and ammunition combination, so testing before critical use is worthwhile.
Yes, this 13-round magazine is designed for both the Glock 23 compact and Glock 27 subcompact. The Glock 27 typically ships with a 9-round magazine, so this ProMag gives you additional capacity if you want it. Keep in mind the longer magazine will extend slightly past the grip on the smaller G27 frame.
Yes, ProMag manufactures this magazine in the United States. The company uses DuPont Zytel polymer and heat-treated chrome-silicon springs in the construction.
ProMag backs this magazine with a lifetime manufacturer guarantee against defects. If you experience a manufacturing issue, you can contact ProMag directly for warranty service.
It's a good idea to test any new magazine with your specific firearm and ammunition before relying on it in a defensive situation. This helps confirm reliable feeding and function with your particular gun. Many people use aftermarket magazines like this for range practice and training before deciding on their use case.
The GLKA11 features numbered witness holes along the side of the magazine body, allowing you to quickly count your rounds at a glance without removing them.
The chrome-silicon spring is designed to resist taking a permanent set even after prolonged storage. That said, rotating through your magazines occasionally during storage is a good practice to keep springs fresh.
