Agency Arms Magazine Extension for Glock 17 +5 Rounds – Sage OD Green

The Agency Arms Magazine Extension adds 5 rounds of capacity to factory Glock 17 magazines, increasing total capacity from 17 to 22 rounds without sacrificing reliability. Designed for competitive shooters and those who prioritize extended capacity, this extension maintains a consistent grip profile while providing additional ammunition for stage runs, range training, or defensive applications.

Machined from 6061-T6 aluminum with a durable Sage OD Green anodized finish, this extension is built to withstand repeated use and maintain its appearance. The extension installs without permanent modification to the magazine—simply remove the factory baseplate, install the included extension spring, and attach the Agency Arms baseplate. No gunsmithing required, though proper installation following manufacturer instructions is critical for reliable function.
