Big Al's got the right cartridge (357Mag), but I'd again recommend it in a rifle.
In a handgun, that cartridge is a handful (no pun intended).
In a rifle, that cartridge is a true pussycat -- I would even say very pleasant.
Also, a scoped handgun is still a real challenge at any real distance, while the
rifle in that cartridge will easily reach out to 100 yards without any real effort.
The rifle can also start a heavy bullet down range 50% faster than a handgun
(1,800 ft/sec vs the slower 1,200 ft/sec). That means the rifle bullet reaches
that 100 yards still going faster than the pistol bullet even starts at.
If it's not too personal, what would impede you using a rifle?
postscript:
I'd also get the
Marlin over the Winchester`92 design as the Marlin is already designed for a scope.
(I say that having got both the Marlin & Winchester)
