Description
The ProMag DRMA27 is a 30-round drum magazine built for Glock 17 and 19 9mm pistols. Made in the USA, it pairs a DuPont Zytel polymer drum with a heat-treated stainless steel spring for dependable feed cycles through hundreds of shots. The injection-molded follower keeps rounds aligned and ready, while side-facing witness holes let you check how many shots you have left without emptying the mag.
The real benefit here is cutting down reload time at the range. Instead of swapping through multiple standard mags, you get 30 rounds in one mag. That means more trigger time and less standing around loading. The compact drum footprint still fits typical holsters and gear setup better than you'd expect from a high-capacity magazine.
ProMag backs everything with a lifetime warranty against manufacturer defects. The magazine springs use precision-wound chrome silicon wire built to handle thousands of cycles, and the whole assembly gets double-checked during manufacturing to maintain quality standards. Whether you're working on speed drills, running competition courses, or just putting rounds downrange, this drum keeps you in the action longer.

Frequently Asked Questions
Will this drum magazine fit my Glock 19?
Yes. The DRMA27 is designed to fit Glock 17 and 19 pistols, along with several other double-stack Glock models like the 26 and 34. Always function-test any new magazine before relying on it for serious use to make sure it seats properly and feeds smoothly in your specific gun.
How reliable is the ProMag drum magazine for shooting at the range?
It's solid for target practice and training. The drum has been field-tested by ProMag's USPSA shooting team and uses a patented follower system designed for consistent feeding. Most people who use them for range work report they perform well through hundreds of rounds.
Can I safely load all 30 rounds into this magazine?
Yes. The DRMA27 loads to full capacity without requiring excessive force or special tools. The injection-molded polymer follower seats properly under spring tension, so loading is straightforward.
What if my drum magazine has an issue?
ProMag covers this with a lifetime warranty against manufacturer defects. If there's a problem with the magazine itself, you can reach out to ProMag and get a replacement. This is a no-questions-asked guarantee that covers the life of the product.
How does this compare to factory Glock magazines?
The DRMA27 gives you triple the capacity of a standard 10-round Glock mag in a more compact drum design than you'd expect. The trade-off is that factory Glock mags have a metal insert throughout, while ProMag uses injection-molded polymer with a steel tower section. For range use, the ProMag performs well and costs less.
Is this magazine made in the USA?
Yes. The DRMA27 is manufactured in the USA by ProMag, using precision-wound springs and careful assembly processes to maintain consistent quality.
