Promag
The Pro Mag S&W M&P 9mm 20-round magazine is a high-capacity aftermarket magazine designed to extend your shooting session between reloads. Built from blue steel, this magazine fits Smith & Wesson M&P 9mm pistols and gives you significantly more rounds on tap than factory-standard capacity options—ideal for range days, competition, or training where swapping mags frequently cuts into your practice time.
Pro Mag magazines have earned a solid reputation in the shooting community for reliable performance at a practical price point. Whether you're a recreational shooter looking to stack more rounds downrange or someone who values having backup magazines in rotation, a 20-round capacity magazine adds flexibility to your M&P setup. Blue steel construction keeps it straightforward and durable.
Like any high-capacity magazine, fit and function can vary slightly between individual firearms, so a function test with your specific pistol is always smart before relying on it in the field or at a match. Having a few options in your magazine rotation—mixing capacity levels to suit different drills—is how serious shooters train.
This magazine is designed to fit S&W M&P 9mm pistols. As with any aftermarket magazine, we recommend a function test with your specific firearm before relying on it in critical use.
A 20-round magazine lets you shoot longer between reloads, which is especially valuable for range training, competition practice, or high-volume shooting days where frequent magazine changes slow you down.
Pro Mag magazines are known for dependable performance. However, individual fit can vary by firearm, so testing it with your pistol before defensive or competition use is best practice.
