Cross Armory 0 Magazine Extension for Gen 1-5 Glock 17/22/31

Description The Cross Armory 0 Magazine Extension is designed to have the slimmest profile, best grip and easiest installation in the industry. THIS IS HOW WE DID IT: We spent months purchasing every magazine extension on the market. The first thing we noticed was that there were a lot of bulky, overweight magazine extensions. We focused on a form factor that reduced the weight of the extension as much as possible, while keeping all the strength. We chose to make our extensions from scratch, out of a solid block of aircraft grade aluminum, which saved weight and kept all the needed strength. This made our Cross Armory 0 Magazine Extension the lightest weight and slimmest profile, solid all aluminum, for a guaranteed smooth drop when empty! Then we evaluated the grip. Most, if not all of the other mag extensions on the market had a weak grip or no true grip at all. We define true grip, as the ability to hold something with wet or bloody hands and/or gloves and pull on it. Noting this, we designed slots in the Cross Armory 0 Magazine Extension that were clean looking, but had a strong 90-degree angled ledge, at the front and at each side with engineered bite to hold your grip without snagging. The extra thought and engineering provided a true grip, for when your life depends on it. Finally, we evaluated the installation and retention of the magazine. It appeared that everyone in the industry was trying to do something different or unique to attach their mag extension to the magazine. With that, they stuck us with wild complexity and over complication in the installation process that baffled even our own engineers (and one is an actual rocket scientist). We chose a new path; we believe that oftentimes the simple solution is the best and most reliable solution. We discarded over complications and went with a simple screw with lock-tight. Clean, easy, reliable installation. We are confident that the Cross Armory 0 Magazine Extension is the best in the industry. We are willing to back it up, with a 100% no questions asked money back guarantee. If you don’t love it, we will give you your $ back. *Magazine not included DISCLAIMER: This product is not manufactured, authorized, endorsed, or warranted by GLOCK.
