Description
The ProMag DRMA35 is a 30-round drum magazine purpose-built for the Glock 43X and 48 platforms. It pairs a proprietary DuPont Zytel polymer drum housing with a full-length steel internal insert in the magazine tower, giving you a smart balance between durability and weight. The injected polymer follower and heat-treated steel spring are designed to feed reliably through all 30 rounds without issues.
Where this drum really shines is at the range. Instead of loading multiple magazines to get through a full practice session, you pack one drum and stay focused on shooting rather than reloading. The compact design on these subcompact Glock frames means you're not dealing with an oversized magazine either. This is a straightforward, no-frills option for volume shooters and training runs.
Made in the USA with a lifetime warranty backing the build quality. If you want to maximize your time downrange without the hassle of constant magazine changes, this is a practical tool that delivers the capacity you're looking for.

Frequently Asked Questions
Will this ProMag 30-round drum fit and function in my Glock 43X or 48?
Yes, the DRMA35 is specifically engineered for the Glock 43X and 48. The magazine tower features a full-length steel insert that mirrors factory Glock feed geometry to ensure reliable feeding. It inserts and seats exactly like a factory magazine.
How does the 30-round capacity compare to standard magazines?
Standard Glock 43X and 48 magazines typically hold 10-15 rounds depending on your location. The 30-round drum more than doubles that capacity, letting you spend more time shooting and less time loading at the range. ProMag also makes a 50-round option if you want even more firepower.
Is the drum magazine heavy or does it add too much bulk?
The drum uses a proprietary DuPont Zytel polymer to keep weight reasonable while maintaining durability. It's bulkier than a standard magazine due to its drum shape, so it won't fit in typical magazine pouches or holsters. It's really built for range work and training rather than carry.
What should I know about loading and maintaining the DRMA35?
Load it like any other magazine, inserting rounds into the top of the drum until full. The polymer construction is easy to clean if needed. Store it unloaded or loaded as you prefer, and the lifetime warranty backs the quality if you run into any issues.
Who would benefit most from this 30-round drum?
Volume shooters, range trainers, and competitive pistol competitors appreciate the extra rounds without the hassle of loading multiple mags. It's practical for breaking in a new gun, running drills, or just having fun at the range without constant reloading breaks.
Does ProMag offer any warranty or support on this magazine?
Yes, all ProMag magazines come with a lifetime warranty backing the quality and construction. If you experience any defects in materials or workmanship, ProMag stands behind the product.
