I have the CZ Hammer Classic 12ga with 3" chambers and screw in chokes. Chokes are good to go for steel up to modified. I intend to use it this Fall for ducks.

It is a heavy gun, but mine balances well. The gun can be opened with the hammers back and it even has a slide safety. Mine has the case colored frame and hardware, but the new ones are blued. A grand will put one in your hands...Geo
