Revolver or auto?
Alot of folks call an auto a pistol ,and a revolver a revolver,... but to me when someone says pistol, I automatically think of a revolver. They are what I grew up with.
Figure out which you want and narrowing the choice will be easier.
Myself, I'm partial to the revolvers. I have a Uberti Cattleman in 45 colt.
It has a 4 3/4 " barrel, but I've bought a 5 1/2" from
www.vtigunparts.com
and will have that put on shortly.
The cattleman is a replica of the 1873 Colt Single Action Army model, and you would be hard pressed to tell the difference in them side by side.
