Description
Need more rounds downrange between reloads? This ProMag drum magazine holds 50 rounds of 9mm and fits Springfield Armory Hellcat pistols. Whether you're putting in serious trigger time at the range or running drills, the 50-round capacity means fewer interruptions and more time actually shooting.
Proven construction built in the USA
ProMag combined traditional manufacturing methods with modern precision here. The drum housing starts with proprietary DuPont Zytel polymer for impact and corrosion resistance, while the upper tower features a full-length steel internal insert that's stamped and welded just like factory magazines. This hybrid design gives you the weight savings of polymer with the durability of steel reinforcement where it counts.
Reliable feeding every time
The internals are engineered for smooth operation. An injection-molded follower works with a heat-treated stainless steel spring to push rounds up consistently, even after a full magazine of shooting. The polymer body is precision-engineered to minimize wobble when locked into your Hellcat, which means better reliability during use. The snug fit prevents binding and ensures the feed lips stay aligned with your gun's chamber.
Made in the USA with a lifetime warranty
This magazine rolls off American assembly lines, not some overseas facility. Every ProMag drum comes backed by a lifetime warranty against manufacturer defects. If anything goes wrong with the construction or materials, ProMag stands behind it.
Note: This magazine is designed for the standard Springfield Hellcat. It does not fit the Hellcat Pro models.

Frequently Asked Questions
Will this drum magazine work with my Springfield Hellcat Pro?
No, this DRM-A51 is designed specifically for the standard Springfield Hellcat. ProMag makes a separate drum magazine for the Hellcat Pro model, so check compatibility carefully before ordering. The standard Hellcat and Hellcat Pro have different magazine wells and are not interchangeable.
Does this magazine really hold 50 rounds?
Yes, the 50-round capacity is the full design. Loaded to capacity, the magazine will be noticeably heavier and bulkier than factory mags, which is why most people use it at the range rather than for carry. The weight of a fully loaded drum is something to get a feel for before heading out to shoot.
Is the steel tower necessary, or is it just extra cost?
The steel-reinforced tower actually matters. That stamped and welded steel insert gives the magazine rigidity where the feed lips meet your gun's chamber, helping ensure consistent feeding under rapid fire or after thousands of rounds. It's a smart design that borrows from factory magazine construction.
What makes this better than cheaper drum magazines?
ProMag's hybrid construction, heat-treated stainless spring, and injection-molded follower system are built for reliability over the long haul. The precision engineering minimizes wobble and binding, and the lifetime warranty backs up the quality. You're paying for magazines that actually feed reliably, not just high capacity.
