I've used a .357 for both mountain lion and mule deer. It is very marginal for deer, and I now use a .41mag or .44 mag.
I have hunted with handguns quite a bit,
Savage Striker in .243
T.C. Contender in .45 Long Colt,
T.C. Encore in .307 Winchester,
I have a couple more Contenders and a few different barrels, along with a couple more Encore barrels. I have also killed a lot of squirrels and rabbits with a Colt New Frontier .22 and a Ruger Standard auto .22.
This is my idea of a handgun.
Had one for years and loved it!

Ruger super redhawk .44 mag topped w/ leupold 4x ler and pachmyer grips. I have only shot 2 deer with it but its main use is for bear and lion protection during summer packing trips with the horses, I don't use the scope with it when I ride. It has a nice magna port on it and had the trigger smoothed. I want to shoot my bear when I draw that tag.
I have taken a pronghorn doe with my XP-100 in 284 Winchester, but I wasn't really all that happy with that pistol.
I am going to build a couple of new ones when I get back to the states on BAT XP-Length actions in 250 Savage, 6mm BR, 358 Win, and 6.5 Creedmor.
I have a Raging Bull in 454, but I haven't shot anything with it.
