I don't know--my test is longevity and reliability. All things being equal, if I were to put my tail on the line, or my Grandkids tails on the line 100 years from now, I'd sooner at the moment of truth a stout wheel gun was pulled from a drawer or safe than ANY automatic now extent. More and more, my thought is--*if* a revolver didn't suffice, you needed MORE gun than an automatic pistol could provide. Revolvers are the one-handed, no safety, no brainer, proven tech that should stay around.
(May G--, JMB, my 1911a1,1903, and MK II forgive me).
