Agency Arms Magazine Extension for Glock 17 – +5 Rounds (Black)

The Agency Arms Magazine Extension for Glock 17 increases standard 17-round magazine capacity by 5 rounds, bringing total capacity to 22 rounds. Designed for competitive shooters and those who prioritize maximum capacity without requiring an extended magazine body, this extension maintains a relatively compact profile while providing additional firepower. The aggressive texturing provides positive grip during reloads under stress.

Machined from 6061-T6 aluminum with a durable black anodized finish, this extension installs without permanent modification to the magazine. Installation requires disassembly of the magazine base plate and replacement with the extension, along with the included higher-tension magazine spring to accommodate the additional rounds. Basic familiarity with Glock magazine disassembly is recommended. The extension adds approximately 0.75 inches to overall magazine length.
