I think I'm jonesing for a new handgun. I like what I'm learning about the CZs. They seem to make some nice firearms. But then again, I might want a Springfield 1911. I don't have a 1911. Or maybe I want that Ruger 1911. Or should it be a Colt? I don't own any 9 mm or .45 ACP. Tell me what you know about any of these. I don't even know where to begin.
