The Promag Smia22 20-round magazine for S&W M&P 10mm delivers reliable capacity and durability for shooters who want to maximize rounds downrange without frequent reloads. Built from heat-treated steel with a black oxide finish, this magazine is engineered to handle the demands of the hard-hitting 10mm cartridge. Whether you're running drills at the range, competing, or training for defensive readiness, a 20-round mag for your M&P 10mm gives you the ammunition supply to extend your shooting sessions and build muscle memory.
Promag constructed this magazine with the same materials and processes that have earned respect in the aftermarket magazine space: heat-treated chrome silicone wire for the spring and an injection-molded follower that guides rounds reliably into the chamber. The black oxide steel body resists corrosion and blends with your pistol's finish. Made in the USA, it's a no-frills, straightforward option for M&P 10mm users who need extra capacity without the price tag of OEM magazines.
A critical note: this magazine is engineered specifically for the S&W M&P 10mm platform and will not function in M&P 9mm, M&P Shield 9mm, M&P Shield Plus 9mm, or M&P Shield EZ 9mm models. Verify your pistol's caliber before ordering. If you shoot one of those 9mm variants, you'll need a different magazine designed for that platform.

No. This Promag is designed exclusively for the M&P 10mm platform. It will not fit M&P 9mm, M&P Shield 9mm, M&P Shield Plus 9mm, or M&P Shield EZ 9mm models. Always verify your pistol's caliber before purchasing magazines.
Heat treatment hardens the steel body to resist wear and deformation under repeated use and the pressure of the 10mm cartridge. The chrome silicone wire spring is engineered to maintain consistent tension and feeding reliability through hundreds of cycles without losing tension or breaking.
This magazine is designed for the S&W M&P 10mm series. If you own a variant or newer generation of the M&P 10mm, we recommend confirming compatibility before use. Contact our team if you're unsure.
