Overview

The frame features a textured grip surface for a secure hold under all conditions, an integrated trigger guard, and a rail section for mounting lights or lasers.

It is ideal for shooters who prefer the ergonomics of the Glock 19 but want to add personal touches like a custom trigger, slide cuts, or a specific color scheme.

This frame is not recommended for first-time builders without some prior experience with firearm assembly, as it requires drilling and finishing work.
