The Smith & Wesson M&P22 Compact was made as the perfect range-training solution, and owners are constantly looking for ways to shoot more and spend less time reloading. Thanks to Pro Mag, now owners can load up on aftermarket magazines designed for this plinking pistol. Each of Pro Mag's Smith & Wesson M&P22 Compact magazines have a body constructed from heat-treated steel, which is finished with a black-oxide treatment that protects against corrosion. Inside the magazine, you'll find an injection-molded follower that tops a magazine spring made from heat-treated chrome-silicone wire. These Smith & Wesson M&P22 Compact magazines made by Pro Mag are designed for .22 LR cartridges only and are available in 10-round capacity. All of the magazines are made right here in the USA.
