Drop-in replacement connector gives an immediate improvement in trigger performance on all Glock®pistol (except the 42 & 43). Provides the same 3.5 lb. trigger profile as the factory “-“ connector, but its highly polished stainless steel surface makes the pull smoother, lighter and more consistent. The trigger will reset more quickly for faster follow up shots and less resistance means no anticipation to jerk the trigger and compromise accuracy. Requires no permanent alterations to pistol, so the factory connector can be reinstalled any time, not that you will want to.
