I have had my 45C for 2 years now. When I first got it 7 plus pounds of trigger pull pretty crisp but almost 8 lbs.
The gritty trigger feel was evident right from the start.
I fired 500 rds through it and truly was hoping the really gritting felling would go away. As a defense pistol I could handle the trigger pull. I also dry fired it at least 500 times not much help there either.
Contemplated the Burwell mods but decided that maybe APEX was the way to go everyone that had used the kit liked the results.
I installed the DCAEK kit took my time about 1/2 hr I was good to go. Gritty feeling GONE trigger pull dropped to 5 1/2 pounds and has stayed there since. Didn't want to spend $90 more bucks on the pistol, likely will never get rid of it so it was money well spent.
I could have handled the trigger pull but that gritty feeling had to go.
I'll go no further with it I can do fine with the take up.
