Strike Industries machines this extended magazine plate (part no. EMPALG17RED) from 6061-T6 aluminum to add reserve capacity to compatible OEM double-stack Glock magazines, adding 5 rounds of 9mm to a Glock 17 magazine or 4 rounds of .40 S&W to a Glock 22 magazine. A slow-drag, no-snag design is built into the plate to smooth out reloads instead of catching on the way home, and the aluminum baseplate adds extra locking security so it stays put under recoil. This is a magazine extension, not a standalone magazine, so it installs onto a compatible factory Glock 17 or 22 magazine rather than replacing it outright. For Strike Industries fans looking to stretch factory Glock magazine capacity, this handgun part is a simple bolt-on upgrade.
