Add two additional rounds to your Glock 42 semi-automatic pistol with our Warne Tactical Glock Model 42 +2 magazine extension from Warne Scope Mounts. Our Warne Tactical handgun magazine extension is a firearm-specific fitment for this Glock model sidearm.

Our black Made-in-America mag extension has finger grooves to quickly strip the magazine from the handgun if necessary. The ergonomic shape allows for easier insertion of the handgun magazine extension.

Warne handgun magazine extensions are available in increased-capacity models and they're available in zero-capacity models for 10 round capacity limits. All are crafted from lightweight aerospace-grade aluminum with a hard-coat anodized finish.
