All I would say is that I believe that if you compared a mixture of 100 revolvers each from Ruger and S&W with 100 semi autos each from those same manufacturers, my bet would be on the revolvers, particularly if you factored in the issue (however that could be done) of defensive uses where nerves could likely induce limp wristing in a semi with nothing comparable from the revolver.

Revolvers require little if any break in, unlike semis. I don't think knowledgeable shooters would use a semi for CCW unless it had 100-200 flawless rounds through it.

A revolver should be "good to go" if it has a flawless cylinder full through it. Don
