Tyrant Designs Magazine Extension for Glock 19/23 Pistols

This is a Tyrant Designs magazine extension with a +5/4 capacity for Glock® 19 pistols. 
Made right here in the USA using CNC fabrication technology, these Glock-compatible baseplates from Tyrant Designs are the cutting edge in magazine extensions. Utilizing their signature retention plunger technology, Tyrant Designs has created a baseplate that can be installed in as little as 10 seconds—all without a single tool. No other baseplate offers easier installation. Made from solid aerospace-grade aluminum, these extensions offer just the right amount of heft, guaranteeing your mags drop-free for faster reloads. The generous grip notch offers a sure hold when pulling from a pocket or magazine pouch, and the full chamfer treatment these receive ensure no sharp edges digging into your hands. Adding an extra 5 rounds of capacity to 9mm magazines and 4 rounds to .40 S&W mags, these extensions will keep you shooting more and reloading less. These extensions come with an enhanced magazine spring. Compatible with Glock factory magazines for models 19 and 23.
