Most Glock builders end up on three or four different product pages, trying to figure out if the barrel they’re looking at fits the slide they want. This configurator solves that. Every component shown is already verified compatible — pick your slide, pick your barrel, pick your internals, and it ships together.
What you configure:
- Slide — multiple finish and cut options for Glock 19 Gen 3
- Barrel — standard, threaded, fluted, TiN, nitride, or other finishes
- Internals — 3CR Tactical slide completion kit included or already selected
- Optional sights — standard or tall co-witness height
All components are pre-verified compatible with:
- Glock 19 Gen 1, Gen 2, Gen 3 OEM frames
- Polymer80 PF940C frames
- GST-9 frames
Assembly required:
Components ship individually. You assemble the slide — the internals drop in by hand with basic tools. If you’re new to Glock slide assembly, the 3CR YouTube channel has a walkthrough.
Why build your own vs. buying assembled:
The BYO configurator lets you customize finish and barrel combination. The pre-assembled slides ship ready to install. Both are priced with 3CR margins built in — no markup surprise at checkout.
