As a side note, you don't need snap caps for dry firing if you install the Cajun Gunworks FP-RP, a solid Carbide steel Firing Pin Retainer Pin. That was the reason CZ went to a doubled roll pin, to try to eliminate roll pin deforming from dry fires. The solid piece from Cajun permanently ends that problem.
Agreeing with the trigger control advice, I was incorrectly taught to always 'squeeze the trigger' if you want accuracy. That's only true of bolt actions & some revolvers, NOT pistols! With semi-auto pitols you pull the trigger as described above or else the gun is all over the place. Ask me how I know....
