Promag
The Promag Mosa3 is a 32-round magazine purpose-built for the Mossberg MC2 9mm pistol. If you're running the MC2 as a carry gun, competition rig, or range workhorse, this blued steel magazine gives you serious capacity for extended shooting sessions without a reload. Promag has engineered this to feed reliably through your MC2's magazine well, so you can trust it on the line or in the field.
At 32 rounds, the Mosa3 transforms your MC2 from a practical carry gun into a force multiplier for training, competition, or tactical use. The blued steel construction matches the MC2's aesthetic while delivering durability for hard use. Whether you're running drills at the range, testing your fundamentals in a match, or simply stocking reliable backup magazines, a high-capacity mag like this is a no-brainer for any MC2 owner.
Promag has built a reputation for producing functional, affordable magazines that work. This isn't fancy—it's straightforward capacity and reliability at a realistic cost. Grab a couple of these and you'll have enough ammo on tap to keep shooting without interruption.
