Turn An Glock into a COA Glock
This guide details the COA (Cut-On-Axis) optics cut for Glock slides offered by GlockStore. The COA cut is a unique design that captures the optic into the slide with a beveled spot, allowing for a lower mounting position. This modification requires a specialized rear sight to ensure a secure fit. GlockStore has extensive experience with this modification, having completed over 30,000 slide modifications.
