I'm gonna say a .500 S&W Magnum with absolutely no porting and 2.5" barrel is the perfect choice...just make sure you use 700gr hard cast loads only! Absolutely NO recoil at all, nope. That, or a short-barreled 4bore shotgun with a pistol grip for those recoil shy folks, otherwise 2bore is the winner. If you can't find either of those, something like a .75cal smoothbore musket will do.
No, really though....we can't pick out a pair of shoes for you...it's no different with guns. There's so many convoluted suggestions in the comments it's likely created you more confusion than given you answers.
