Poor fellow, your limiting yourself to one? I have more than one car, motorcycle, handgun, wo*** and fly more than one airplane. If forced, my one handgun would be a .357 with a 4-6" barrel. The best part of a .357 is its 38 special capability. The best part of a 44 magnum is 44 special. A single action 45 is always special but is never a 686 or Python. The older I get, I find myself enjoying a lot of 38 special these days along with 44 special and 45 Colt in a SAA or New Frontier. Specialty calibers are usually more or a burden than pleasure. Have fun and just my .02.
