I did put a Yodave trigger kit in the CZ, and if it had a better trigger I believe it would hang in with my Cooper for grouping.
I hear ya...I'm a real trigger snob so I put a Basix in mine before I ever fired it.
In looking at the web-site for Rifle Basix for the 452 they do not go into detail about the sear adjustment, did you use that feature, and if so, is it "fine-tunable" or more of a coarse adjustment?
I am thinking of ordering one and can't really seem to find much info on them.
Thanks, drover
