Promag
The ProMag SMIA15 is a 12-round 9mm magazine purpose-built for the Smith & Wesson M&P Compact, giving you reliable capacity in a package that fits your carry or duty gun. Whether you're stocking spares for the range, building out a defensive loadout, or just want backup mags on hand, this blued-steel magazine is engineered to handle repeated loading cycles without losing spring tension or function.
ProMag designed this magazine with heat-treated blued steel for durability and corrosion resistance, paired with proprietary Technapolymer components that reduce wear and extend service life. The anti-fatigue spring design means you can keep the magazine fully loaded for extended periods without worrying about spring degradation—a real advantage when mags are staged for duty or competition use.
At 12 rounds, this mag gives you a capacity boost over single-stack alternatives while maintaining the compact profile M&P shooters expect. It's a no-frills, functional choice for shooters who need dependable spare magazines without premium pricing.
