There is a couple of other options. I carry a 396. L frame 44 special. Not as powerful as a 44 mag, but at biting range it would be very effective. Also there is the 325. Again not in the power range of the big 44, but a heavy 45 caliber bullet isn't going to bounce of something made of flesh.

But, the big thing in YOUR decision is now YOU tolerate the recoil and handle which ever you chose. To me the perfect light gun with the most umpha would be a 325 in 45 Colt. Biggest bullet, decent power and I am a 45 colt lover.
