Agency Arms Magazine Extension for Glock 19 15rd +5 Black

The Agency Arms Magazine Extension adds 5 rounds to factory Glock 19 15-round magazines, bringing total capacity to 20 rounds. This extension is designed for shooters who want increased capacity without moving to a full-size frame, whether for competition, duty, or personal defense. The extended baseplate maintains a clean profile while providing a secure grip purchase and reliable feeding.

Machined from 6061-T6 aluminum with a Type III hard-anodized black finish for corrosion resistance and durability. This is a drop-in installation that requires disassembly of the magazine—no permanent modification to the firearm or magazine tube. Includes extension baseplate and extended spring to ensure reliable function at the higher capacity. Factory magazine follower is retained.
