ProMag SMIA23 S&W M&P 9mm 20-Rd Blued Steel Pistol Magazine

The ProMag SMIA23 is a 20-round replacement magazine designed for the Smith & Wesson M&P9 series of 9mm Luger pistols. It is a solid option for range sessions, training, or home-defense use.

The magazine body is precision-constructed of heat-treated steel finished in a blued (black oxide) coating for corrosion resistance and long service life. An injection-molded polymer follower and steel spring provide consistent feeding. The combination of a steel body and polymer follower makes this a durable option for extended range sessions.

This magazine is designed to fit S&W M&P9 9mm series pistols. It does not fit the M&P Shield, Shield Plus, or Shield EZ variants, which use a different magazine profile.
