A kid at work had one in .40 had a bunch of problems , luckily his aunt works for CZ had it in a couple times with jamming issues, come back work for a while then same. Finally the 3rd time he got it back service guy asks if he has been oiling it? His repsonse"Um I didn't know I had to!?" :rofl:
I guess for some reason they expect you to oil for some reason.
Seriously though his is trouble free now and besides HEAVY(not horrible) DA pull it feels good never shot it, but weight, grip, size don't feel bad. I would probaly grap one in 9mm if I didn't have long wish list of others.
Plus CZ CS is great to deal with, will do anything to make sure you are pleased.
