Considerations & Trade-offs
- Requires a compatible Glock Gen 3 setup in 17, 19, or 34; it is not a universal fit.
- Uses the standard 1/2x28 thread pitch, so compatibility depends on having the correct threaded barrel setup.
- Designed to work with the OEM recoil spring assembly, which limits tuning options if you prefer a different spring setup.
- The front sight hole supports transferring an existing front sight, but that also means sight compatibility depends on your current slide and sight arrangement.
