Let's get some clarification first -
Are you talking about regulation trap and skeet or backyard stuff?
Second, what's your budget?
Third, open to buying used?
Fourth, how many shots per year?
I own a Turkish gun (CZs are made in Turkey), but it is a field gun. I have no illusion about it being able to shoot the volume that target shooters go through. If you will be shooting a lot, ammo and target fees will easily cost more than your gun in a few months. Since the gun is the least final cost over the long haul, buy the absolute best gun that FITS that you can. As mentioned above, the BT-99 is about the best trap gun for the money available; however, it is built for one purpose only - shooting trap singles. If your budget is tight, a better quality semi is far and away better than a low end O/U. I have right about 300,000 through a Browning O/U that I shot for 20+ years. Bought that gun when it was discontinued and can sell it now for more than what I paid for it. It needed some springs and I also had them replace the firing pins at 90,000. Averaging about $0.40/bird and ammo, that's $120,000 spent shooting a gun that cost me $1K. Buying a cheap gun that might spend more time in the shop is not the best way to go about this.
