For years, if you wanted more than 30 rounds in a handgun magazine, your only option was to go with Glock-pattern mags. Today, though, thanks to the huge number of Springfield Armory XD handguns on the market, these aftermarket mags make it possible to extend your trigger time at the range. The Springfield Armory XD steel magazine is designed for use with 9mm models only and have a magazine body made from heat-treated carbon steel. The magazine is treated with a black-oxide finish that combats corrosion and premature wear. Inside each Springfield Armory XD-9 steel magazine, you'll find a spring formed from heat-treated chrome-silicon wire, as well as an injection-molded follower. The magazines are available with a 32-round capacity and are made in the USA.
