mccoy: Although I have a preference for semi-autos, I also enjoy revolvers very much. The problem in doing a comparison is that there are so many to choose from on either side. I haven't noticed that one type has a greater accuracy than the other, but I have noticed that people are often a better "fit" for one or the other. I shoot the same going between the Glock G30 (.45) and the Ruger GP100 (in .357) and I love them both.
Regarding the need for firepower, I can only say that it is better to have and not need than to need and not have. It's not that things are so tough out here (I stand an excellent chance of reaching the end of my life without ever needing a firearm) but most Americans approach the idea of self-defense from a strategic and tactical point of view. Semi-autos offer more rounds and a much quicker reload; and the polymer frames are much lighter. These are advantages although they don't in any way render the revolver obsolete.
I am a semi-auto man. But I will defend any law-abiding citizen who favors the revolver because we are more alike than different. Keep shooting, friend!
