Never owned anything but an 870 sps-t super mag. Anynice 12 ga.will do though, it's not that big of a deal. Just whatever you feel most comfortable with. I shoot a .660 constriction primos tightwad choke, with 3.5" federal #5's. Also I would suggest using open bead sights, unless you're hunting open country and anticipating long range shots. I've never used a scope on a turkey gun, but I've had way too many close shots at 20 steps or less where I've had to throw up and shoot quickly, and I know a scope would have made a lot harder to get on those birds. It has a lot to do with what type of terrain you're hunting too.
