Let me find the book with the info, and I will quote it in thread form.
I agree with the Butch & Sundance post. Carry 'em all.
Sure am glad this thread is hypothetical. I'd hate to be limited to one.
If I ever find a good deal on a stainless ROA, I'm jumping on it. Provided I can afford to buy it, of course. I've wanted one since I was a kid. It's a hoss.
Then again, I've always wanted a Colt Walker, '69 Mach 1, Hemicuda, '71 Mach 1, '72 Torino GT, '63 Sting Ray, Dart GTS, Demon 340, '72 Satellite Sebring, '67 Nova SS-327/4 speed, etc.
Still don't have any of them. It kinda bites, not being rich.
If any of the fine folks here would like to donate a Ruger Old Army to me, so I could carry/shoot it and decide that it could be my 1 and only C&B revolver, I'd be more than happy to oblige them.
