glock trigger with trigger bar (gen 3 sub/com)
The smooth faced Gen 3 trigger bar (357) is one of the most popular upgrades to Gen 4 pistols among owners who want to improve trigger smoothness while still using proven Glock OEM parts.
Compact and Sub-Compact framed pistols have grooved trigger faces, as opposed to the smooth faced triggers on the Full and Competition size pistols.
Either trigger bar fits in all 9mm / .40 S&W pistols, the only difference is the trigger face, so it comes down to shooter preference.
.45 ACP pistols use the Gen 4 trigger bars.
Frame size specific:
- Compact / Sub-Compact (19 / 23 / 26 / 27) - Grooved
- Full Size / Competition (17 / 22 / 34 / 35) - Smooth faced
