ProMag SMIA21 .22 LR 12-Rd Steel Magazine for S&W M&P 22 Compact - Black Oxide

The ProMag SMIA21 is a 12-round .22 LR replacement magazine purpose-built for the Smith & Wesson M&P 22 Compact series of rimfire pistols. Designed as a reliable spare or replacement for this widely used rimfire training and plinking platform from S&W, this magazine brings ProMag's well-known blend of value and durability to the rimfire market.

The magazine body is constructed from heat-treated steel finished in a low-glare black oxide coating for corrosion resistance and long service life. An injection-molded polymer follower and steel wire spring combine with the rigid steel body to deliver smooth, consistent feeding round after round, making this magazine an excellent companion for extended range sessions and high-volume rimfire practice.
