Shield Arms Magazine Extension +5/4 for Glock 17/22 – Gold

The Shield Arms Magazine Extension adds 5 rounds to factory Glock 17 magazines and 4 rounds to factory Glock 22 magazines, increasing capacity without sacrificing reliability. Designed for shooters who need maximum round count for competition, duty, or extended range sessions, this extension maintains the magazine's feeding geometry while providing a substantial capacity boost.

Machined from aluminum with a gold anodized finish, the extension installs without permanent modification to factory magazines. Installation requires disassembly of the magazine baseplate and replacement with the Shield Arms extension and included spring. The extension adds approximately 0.75 inches to overall magazine length. Factory magazine springs should be replaced with the provided extension spring to ensure reliable feeding at increased capacity.
