Long story short finally found one of these bad boys and the day I picked it up I took it out shooting and fired 200 rounds of factory ammo and noticed my bullets were tumbling. During cleaning I found that the rifling was damaged and a hair line crack on top of the barrel. Contacted CZ and they gave me a shipping label to return but it's a 6-8 week turn around. I can't wait that long especially because I already waited the california awesome 10 day hold. I want to run this gun for production uspsa next Saturday... does anyone know a site I can buy it from that has it in stock? I know I'm being impatient and gonna lose money... but because CA gun roster and laws, I'm going to run this gun in competition so once I find another one I will send the original in for warrant.
