Description
The LCP is a brilliant little carry gun, but anyone who has run one at the range knows the drill: a few seconds of shooting, then back to reloading. ProMag's DRM-A39 drum magazine flips that script by packing 32 rounds of .380 ACP into a format that locks right into your LCP just like any other magazine. That is more than four times the factory capacity, which makes a real difference when you are working on fundamentals or just want to enjoy a longer string of fire without constant interruption.
The construction is a hybrid of DuPont Zytel-based polymer for the drum housing and a blued steel upper tower. The feed lips are overmolded stamped steel, which helps keep things stable and wobble-free at the mag well. Inside, you get an injection-molded follower paired with a heat-treated chrome silicon wire spring that is precision wound for consistent tension round after round. The loading mechanism uses a turn-dial system, which makes topping off the drum more manageable than you might expect for a 32-rounder.
ProMag makes this one right here in the USA, and it carries their lifetime warranty against manufacturer defects. That kind of backing matters when you are buying an aftermarket magazine, and ProMag has been producing US-made magazines long enough to have a real track record in the market.
This is primarily a range and training magazine. The added bulk of a drum format is not going to work for everyday carry, but for getting quality trigger time with your LCP without burning through a stack of flush mags, it is genuinely useful. It also works with the LCP II.

Frequently Asked Questions
Does this drum magazine fit the Ruger LCP II as well as the original LCP?
Yes, the ProMag DRM-A39 is compatible with both the original Ruger LCP and the LCP II. Both pistols share enough design similarities at the magazine well to accept this drum. Always do a test fit before heading to the range to make sure everything seats and locks up cleanly.
Is this drum magazine difficult to load?
It uses a turn-dial loading mechanism, which is a lot more straightforward than it might look. You wind the dial to tension the spring, drop rounds in, and repeat. It takes a little practice the first time, but most people get the hang of it quickly.
Is this a good option for everyday carry?
Not really, and that is by design. The drum format adds bulk that simply does not work for concealed carry in a pocket pistol role. This magazine shines at the range for extended practice sessions where you want to spend more time shooting and less time reloading.
Who makes this magazine and is it backed by a warranty?
ProMag Industries manufactures this magazine right here in the USA. It is covered by their lifetime warranty against manufacturer defects, which is a solid assurance for an aftermarket magazine at this price point.
What is the build quality like on the ProMag LCP drum?
The drum housing is built from a DuPont Zytel-based polymer, which is a tough, glass-reinforced nylon material used widely in the firearms industry. The upper tower is blued steel, the feed lips are overmolded stamped steel, and the spring is precision-wound heat-treated chrome silicon wire. ProMag says every step of assembly is inspected for consistent quality.
Will the extra weight of a 32-round drum affect how the LCP shoots?
It will, at least until you get used to it. A fully loaded 32-round drum adds noticeably more weight to the grip end of a pistol as light as the LCP. Most people adjust to it after a magazine or two, and it is really not an issue for range use where you are shooting from a supported or two-handed stance.
