The Pro Mag Sig SP2340 .40 S&W 50-round drum magazine transforms your SP2340 into a high-capacity platform for range sessions, competition shooting, or training drills. Where a standard magazine tops out at 12 rounds, this drum lets you run extended strings without reloading, keeping your focus downrange and your trigger time maximized. Built tough in the USA, it's engineered to handle the rigors of serious pistol work.
Capacity and reliability are the whole point of a drum magazine, and Pro Mag's design delivers both. The body uses a proprietary DuPont Zytel-based polymer that resists impact and wear—critical for a high-round magazine that'll see heavy use. The blue steel upper tower adds structural support where the most stress concentrates, while the injection-molded follower ensures smooth, consistent feeding. A heat-treated stainless steel spring maintains tension across all 50 rounds, so you're not dealing with weak feeding or jams toward the end of the load.
This drum fits the Sig Sauer SP2340 .40 S&W pistol specifically. It's a game-changer for shooters who want to run more rounds per magazine—whether you're at the range burning ammunition, running a training course, or simply want fewer magazine changes during a session. The black polymer finish matches tactical setups and stays low-profile in a range bag.

Yes—this Pro Mag drum is designed specifically for the Sig Sauer SP2340 in .40 S&W. Make sure your pistol is chambered in .40 S&W, as it will not function in other calibers or SP2340 variants chambered differently.
A drum magazine holds significantly more ammunition—in this case, 50 rounds versus the SP2340's standard 12-round capacity. The circular design and spring mechanism work differently than a traditional box magazine, allowing you to load more rounds in the same footprint and run longer without reloading.
This is a range and training magazine. We recommend standard factory magazines for carry or duty applications where absolute reliability under all conditions is critical.
You receive the Pro Mag 50-round drum magazine. We recommend testing it thoroughly at the range before relying on it for extended shooting sessions, as with all aftermarket magazines.
