Are they necessary, probably not. Are they beautiful, accurate, well fitted, & a real pride to own? Yes. I also think a nice old military 1911 is beautiful to own. I also think a current production 1911, particularly a Colt, is beautiful also. I don't own a custom, but have shot several. I can be content with a nice commercial 1911. If someone wants one & can afford it, I say get one.
