Thought I'd do a little work on my CCS gun. The trigger is in very good shape from factory not to loose or to tight. I did adjust on the spring some but still seemed a little to stiff even with the adjuster bottomed out so I started cutting ;D I'm not sure how much I cut off but you can see where I'm at and is a VERY light pull!! I cleaned up everything and de-burred all the parts and adjusted the trigger stop. I'm very satisfied with the smoothness now :-* :-* I done the bump test and all was fine..

Polish and lube all the contact points in the trigger group and you will have done all that you can resonably do to greatly improve the stock trigger. Excellent job!
