Relying on factory ammo for major power factor has not led to a great experience for me. Purchased a major manufacture ammo that should have met the criteria and velocity was a 150 fps short. Bottom line they would not fix the issue as the lot had passed their inspection and chamber/barrel differences were their explanation of the problem. The rest of that very expensive case was practice ammo.
My pistol was a Tactical Sport.
Reloading is also an issue with CZs as they have tight throats. You need to find your max OAL for the pistol and stick to it. I found loads that would work, but most involved VV powders and magnum primers, which is not in any loading book and would not recommend it to even average reloader, certainly not for mass production.
My eventual conclusion is that if I need major power use a cartridge that starts easily in the major class. 40 S&W does that nicely and loosing 2 rounds out of a 22 round mag means I need to concentrate on the fundamentals than the next guy. Can't miss fast enough to win.
Best wishes to you on your project.

By the way two other competitors were working on this at the same time I was. They both destroyed their perfect Glocks.
