Agency Arms Magazine Extension for Glock 17 +5 Ronin Red

The Agency Arms Ronin Magazine Extension adds 5 additional rounds to standard Glock 17 magazines, bringing capacity from 17 to 22 rounds. Designed for competition shooters and duty use where higher capacity provides a tactical advantage, this extension maintains reliable feeding while reducing reload frequency. The Ronin Red anodized finish offers a distinctive look while protecting against corrosion and wear.

Machined from 6061-T6 aluminum with a Type III hardcoat anodized finish in red, this extension installs using the factory magazine spring and follower. Installation requires basic disassembly of the magazine and replacement of the factory baseplate—no gunsmithing required, but proper installation is critical for reliable function. The extended body integrates smoothly with the magazine tube and includes a reinforced basepad for drop protection.
