XT3033401) that adds 5 rounds to a standard 17-round Glock magazine for a 22-round total capacity. The two-piece housing uses Xtech’s patented "Leading Edge" feeding technology along with an extended 17-7 stainless steel spring for reliable cycling under the added load. Five points of contact on the housing give a secure grip during fast reloads, and the extension fits Glock 17 Gen 3-5 pistols and compatible clones, plus factory 15-round magazines.
