First of all is the sheer beauty of the Western style Single Action revolver. The combination of blue steel, case hardened colors, and walnut, ivory or especially, stag grips. And the ease of disassembly which allows swapping out parts such as brass grip straps and hammers. And the feel of the gun in the hand, as if God made the hand for a Single Action revolver.
But there is a practical side, too. The frame of the Single Action is inherently strong, without cut-outs for the crane assembly, etc. And it is as accurate, or can be made to be, as any other handgun. And, bieng a revolver, it can digest pipsqueak handloads up to the most fire-breathin' cartridges.
And, while I'm not into such ornament myself, no other handgun wears plating and engraving and ivory quite as well as the Single Action.
I revere the revolver so that I capitalize the words "Single Action."
Do I make my point?
