The Pro Mag DRM-A35 is a 30-round drum magazine built for the Glock 48 and Glock 43X in 9mm. It's aimed at range shooters and competitors who want extended capacity without swapping platforms, taking the slimline G43X or G48 from its factory 10-round footprint to a full 30 rounds in one feed device. The drum runs a DuPont Zytel polymer housing over a full-length steel internal insert, so it gains capacity without picking up the bulk you'd expect from a steel-bodied design. If you shoot a 43X or 48 regularly, this is a high-volume option for fewer reloads between strings.
Construction starts with a proprietary DuPont Zytel-based polymer drum housing wrapped around a full-length steel internal insert that is stamped and welded like a factory magazine feed lip and body. Feeding is handled by an injection-molded polymer follower riding on a chrome silicon wire spring, both chosen to hold tension and geometry across the 30-round stack. Per manufacturer specifications, the magazine measures roughly 3.10 by 5.30 by 13.95 inches and is made in the United States. Pro Mag backs it with a lifetime guarantee against manufacturer defects. The result is a drum that adds capacity to the 9mm slimline Glocks while keeping the steel-reinforced feed path that matters for reliable presentation under load.
This drum earns its place at the range, in training rotations, and on the clock during pistol-caliber competition where round count between reloads is the limiting factor. Run it with the same 9mm load you trust in your standard mags and confirm function before any serious use. It's a 9mm Glock 43X and 48 fitment only, so check your pistol before ordering.

The DRM-A35 is built for the Glock 48 and Glock 43X chambered in 9mm. It is not intended for other Glock models or calibers. Confirm your pistol is a 9mm G43X or G48 before ordering, since fitment is specific to those two slimline frames.
It holds 30 rounds of 9mm. That takes the standard 10-round 43X or 48 magazine footprint and triples it in a single feed device, which means fewer reloads during range sessions, training, and pistol-caliber competition.
The housing uses a proprietary DuPont Zytel-based polymer over a full-length steel internal insert that is stamped and welded like a factory magazine. It feeds with an injection-molded polymer follower on a chrome silicon wire spring, keeping the steel-reinforced feed path while staying lighter than a full steel body.
Yes. Per manufacturer specifications, the DRM-A35 is made in the United States and carries Pro Mag's lifetime guarantee against manufacturer defects. As with any high-capacity magazine, run it with your trusted 9mm load and confirm function before relying on it.
