+5 horsepower! - ZEV Technologies Glock 17 9mm Luger +5 Round Pistol Magazine Extension

One of the best mag extensions I’ve used thus far! Super easy installation and easy to remove, unlike some other brands, if you want to put them from an old mag to a new one. Looks awesome to boot, and the spring is nice and strong. Can’t go wrong if you’re trying to get a little more Bang for your buck. (Only works on Glock oem mags.)
