edamon2k, STI is a small semi-custom manufacturer and they literally grew from the IPSC market. They started making hi-cap frames and eventually expanded into complete guns.
As far as Production division, all guns must be double action (and Glocks are considered DA for this division), so a SA CZ would not be legal for Production.
Production also has a 10 round/mag limit so hi-caps are no advantage.
I suggest you join the USPSA. You get a great semi-montly magazine for it, and find a USPSA affiliated club near you. Go your first match to just watch. Find the match director and ask him if there's somebody who will take you along with their squad and explain everything that's going on. It's important to have some contacts that know the game.
Good luck and DVC!
