RE: Any Pistol Hunters?
I woud first ask what yo plan on hunting, ranges you'll be shooting and what your comfortable with. Have you ever shot big bore handguns before?
In any case should you be hunting deer which from you post, looks like the case. I would go with nothing less than the 41 mag. in a revolver. Revolver chamber choices can run from the 41 up to the massive 500 S&W. If your are going to use this handgun strickly for hunting you may want to consider a T/C encore or contender G2. There you have a wide selection of chamberings. YOu can get a .22 LR barrel for practicing and get a "deer" chambering in 7-30 (My favorite in my contender) Waters on up to 45-70. You can even get 308 or 30-06 in the encore. And if you decide handgun hunting isn't for you, all you need to do is get a carbine barrel and stock and you have another rifle.
My final opinion is if you decide on a revolver would be a S&W or Ruger Redhawk in 44 mag. or a 7-30 Waters or 35 Rem. in the T/C Contender or 7mm-08 or 308 in the Encore.
And practice, practice, practice.
