My wife's CZ-75B SA was sent to CZ for trigger job and since she got it back we've been getting intermittent lite strikes. She can re-cock the gun and get them to go off on the second or third try, but I'd like to just swap the spring out and be done with it.
What weight CZ-75 main/hammer spring will reliably set off CCI primers? 15lb?

My SP-01 Shadow has 13 lbs mainspring from Angus. Have never had any malfunctions with CCI #500 primers or any other brand.
In SA gun mainspring has little to do with trigger pull weight. Put 15-16 lbs spring if you feel the problem is mainspring.

a full 13# or 15# mainspring should set off everything..
I'm running a 15# clipped two coils in one gun and it'll run Speer Lawman ammo perfectly.
my other one with a 13# clipped need a little more tweaking..but it will set off everything now too.

Good info, I've got several main springs and did not want to ruin the trigger pull by putting something too stiff in it. I'll go ahead and try a 15 or 16lb and see if it helps.
Thank You.

Thanks, but the ammo is not the issue.
How do you know that, just out of curiosity?
Pride and fear are emotions, which hope for an outcome. Outcomes take your attention from the present, where the shooting happens, to the future. It is totally impossible to do anything in the future, because it hasn't happened yet. The key to shooting your best is to be present as the witness of the shooting. Do not judge, do not give yourself anything to live up to. We can only shoot as well as we have trained ourselves to shoot. To try to shoot only induces stress. Be content with your current ability. And accumulate practice to improve that ability. Consolidate, build strength where you feel weakness. We cannot raise our ability until we accept our current limitations. Practice dissolves limitations. Matches simply define where the current limits exist. The game of shooting is all about redefining our limits.

About four years ago I sent my CZ to Angus for conversion to SA only. It came back with a very light trigger, awesome! But I got the light strikes as you described. I switched to a 16lb hammer spring and the problem went away. Later I went to a 18lb spring to increase the pull weight.

Very light triggers usually come with a caveat: use Federal primers only.
