ProMag SMIA15 9mm Luger 12rd S&W M&P Compact Blued Steel Magazine

The ProMag SMIA15 is a 12-round aftermarket replacement magazine built specifically for the Smith & Wesson M&P Compact in 9mm Luger. It serves as a reliable spare or substitute for the factory mag, adding one more loaded magazine to your rotation for duty, training, or range day.

The body is formed from heat-treated steel with a tough black oxide finish for corrosion resistance and long service life. Inside, an injection-molded polymer follower keeps rounds aligned for smooth, consistent feeding. The detachable double-stack design locks positively into the M&P Compact magazine well and drops free cleanly when the release is pressed.

Whether you need to replace a worn factory unit or just want an extra 12-round magazine on hand, the SMIA15 delivers ProMag's signature combination of steel-bodied strength and affordable aftermarket value.
