I just ordered a sear from czcustom.com it's supposed to shorten your reset to pre-b settings.
Hopefully this works.

The sear arrived and next week it'll be fitted. I'll get my pistolsmith to take before and after photos.

Wow! Of course no pics! However, totally new pistol. Seriously, I bought CZ Customs SAO trigger, took out the firing pin block and with the short reset, it'll run with a tuned 1911. $95 to get the stuff to Canada, a bunch of foul language directed at the Dirty S.O.B. that invented roll pins and the CZ-75 is crisp with no take up and very little over travel.
Not one to be happy and leave it alone, it's getting a new 5.5" barrel, the bushing is coming out and a coned compensator will complete the updates.
