The 1911's a good thing to copy- it just works.
If SIG builds it, it will be as good or better than the Kimber; that's my .02 worth.
As to the other comments, consider: A Harley with $5k of chrome hung on, is still Just a Harley.
The sights, etc for the Colt/ JMB pistol just make it MORE, without ever compromising a(n) uniquely functional and reliable design.
Here's a question: The stuff gets deep, and you can only have ONE handgun, no spare parts. To what weapon would YOU trust your life??
Admittedly, we are on the 1911 forum, but , if somebody knows how to split this post and put it elsewhere, feel free.
My vote, for the only candidate, goes to the 1911 in any flavor. I don't think even the Chinese can F*** it up.
