ProMag DRMA27 StandardBlack Drum 30rd for 9mm Luger Glock 17/19

The ProMag DRMA27 is a 30-round drum magazine for Glock 17 and Glock 19 9mm pistols, engineered to give you serious round capacity when you need it most—whether you're stocking up for competition shooting, training days, or home defense. Unlike stick magazines that eat up pocket space, a drum magazine like this one lets you load deep without multiplying the gear you carry, making it a popular choice for shooters who want to minimize reload cycles downrange.

Built from durable DuPont Zytel-based polymer, the DRMA27 combines lightweight construction with the rigidity needed to reliably feed round after round. The injection-molded follower and heat-treated stainless steel spring are designed to cycle reliably through your Glock's chamber, and the magazine is manufactured in the USA—backed by ProMag's reputation for no-nonsense magazines that work when it matters.

A 30-round drum magazine for your Glock 17 or 19 opens up options: faster splits and longer strings of fire on the range, extended capacity for home defense scenarios, or simply the ability to practice more between magazine changes. This is real-world capacity for real shooters, not a gimmick. If you run a Glock 9mm and want to maximize your magazine footprint in a single load, this is worth serious consideration.

How reliable is a drum magazine compared to standard stick magazines?

ProMag's drum magazines use proven components—injection-molded followers and heat-treated stainless steel springs—designed for reliable feeding. Drum magazines do introduce a different load path and geometry compared to stick mags, so we recommend testing it thoroughly at the range before relying on it in a critical situation. Like any magazine, break-in, maintenance, and the specific firearm can all affect performance.
