ProMag DRMA36 StandardBlack DuPont Zytel Polymer Drum 30rd for 9mm Luger Sig MPX

The ProMag DRMA36 is a 30-round drum magazine built for the Sig Sauer MPX 9mm, designed to maximize your magazine capacity at the range or in the field. Whether you're running carbine drills, testing your MPX's reliability with high round counts, or prepping for duty work, a drum magazine adds serious utility without swapping out frequently. ProMag engineered this one with durability in mind: the upper housing is heat-treated stamped steel with a black oxide finish for corrosion resistance, while the magazine body is injection-molded from DuPont Zytel polymer — a tough, lightweight composite that handles the stress of rapid loading and extended use.

Drum magazines reward shooters who value volume and versatility. The stainless steel wire internals are also heat-treated, so the feeding system is built to endure. Assembly and loading follow the same principles as standard MPX mags, but the larger footprint and weight distribution mean you'll want to test your magazine pouch or gear setup before taking this into the field. Made in the USA, the DRMA36 combines domestic manufacturing with proven materials.

If you shoot an MPX regularly, adding a 30-rounder expands your options. Drums excel for training days, qualification courses, and competitive drills where frequent reloads cut into your shooting window. Just remember: like all high-capacity magazines, function improves after a break-in period and proper loading technique.

Frequently Asked Questions

Will this drum magazine work with my Sig MPX?

Yes. The ProMag DRMA36 is designed specifically for the Sig Sauer MPX in 9mm. Always verify fitment and function before relying on any magazine in a critical application.

What's the advantage of a 30-round drum over a standard stick magazine?

Drum magazines hold significantly more ammunition, which means fewer reloads during range sessions, training drills, and qualification courses. The tradeoff is increased weight, bulk, and a longer break-in period compared to traditional magazines.

What materials is this magazine made from?

The upper housing is heat-treated stamped steel with a black oxide finish. The magazine body is injection-molded DuPont Zytel polymer, and the internal spring is heat-treated stainless steel wire. This combination balances durability, corrosion resistance, and weight.

Is this magazine made domestically?

Yes, the ProMag DRMA36 is manufactured in the USA.
