I have a 45c that had a gritty 6-7lb trigger on it new. Shot a few hundred rounds through it and the trigger smoothed out to about 5.5-6 lbs with some creep.

Put in an APEX hard sear and a USB. Trigger pull now is crisp and reset is fast. On a Lyman trigger pull gauge it is: 4.5lbs and it has transformed this gun for me from another tupperware pistol, to a real shooter. This is the ONLY semi-auto I carry for defensive purposes.
