I usually carry my Kahr PM9 but I have had my eye on the CZ for a little while now also.
As far as the comment with the CZ52, I will be buying one of those next. That 7.62x25 is one mean ass round. I've had my eye on a couple locally, but havent "pulled the trigger" on one yet. You can find them on gun broker for 200ish, and locally they want 275-300. Pretty damn high considering what they sold for 3 years ago.
Glad to hear all the positive remarks on the gun. As far as the cold weather, It doesn't get 30 below here in indiana. Maybe -15 on the coldest day.
I also had no idea this was a call of duty gun. Was it effective in the game?
