I have my CZ 85 Combat with the lighter main/hammer spring (16-17#s?) and a CZ Custom shop competition hammer. I've smoothed everything inside and it is a great shooter. It has given me a light SA trigger. Most accurate gun I have.
My problem is I shoot many different handguns and the SA is almost too light so when I switch between firearms it is so easy (nice problem to have) that it can go off before I really want it to. Also, I don't want to give up the smooth DA. It has been a while since I've had it apart, so I not sure what I can tweak (trigger return spring?) to give the trigger a little more resistance on the SA pull. Thanks in advance for your comments.
