A Ruger .22 Mark automatic series, unless your prefer cowboy look and then you go to the .22/.22 magnum (comes with both )in the new single six. They also make this gun larger, called a blackhawk in .357. Check the lbs. energy of the .22 magnum, I've seen deer to mountain lion dropped like lead by the .22 Magnum. I think you'd like .22 mag. because it has an extra bump that makes is a fine coyote gun in it's own and it's much cheaper to shoot, far less recoil, which always results in better accuracy. You might check out the .327 Fed Mag in the two versions by Ruger. Regardless it will be fun if your hunting w/a pistol. I'm setting up my fall deer/coyote pistol now, a 10" stainless bull barrel, 8 shot .218 Bee Revolver, think Ill top w/2x7 burris w/MilPlex scope. I've stacked my share of deer, turkey and varmints with the .218 Bee. Be safe, have fun.
