You "collect" much the same as I do, David!
I have Colt, Ruger, Smith, North American Arms, Kel-Tec, High Standard: I have revolvers and autoloaders, single actions and double actions, all shapes and sizes and calibers and finishes and barrel lengths.
And I bought them because I managed to convince myself that I "need" them for "protection"! Which is nothing but an excuse to buy another one I don't need.
