PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.

What it does
This extension replaces the factory baseplate and increases magazine capacity while giving you a larger gripping surface for reloads. It is built for shooters who want more rounds on tap for competition, training, or duty-style setups.
Why it’s worth it
