ProMag Standard 15rd 40 S&W Compatible w/Glock 22/23/27 Black DuPont Zytel Polymer GLKA12

In the market of expanded capacity magazines for Glock handguns, most manufacturers focus on 9mm options at the expense of other calibers that continue to be popular with today's handgun owners. One of those often-forgotten calibers is the .40 S&W, and these Glock 22/23/27 polymer magazines offer expanded options for more mags, as well as an increased capacity option that holds up to 27 rounds.

Each Glock 22/23/27 polymer magazine is built for use with the .40 S&W cartridge, and the magazine body is constructed using DuPont's proprietary Zytel polymer, which has been proven to be durable and long-lasting. Constant spring pressure is provided by a heat-treated chrome-silicon wire spring. The magazine are all made in the USA and feature an all-black finish.
