Was it the "tactical version" or normal one. I know a lot of folks buy them to build off of. 1911 parts are abundant so they buy the cheapest Rock Island version they can get and put the performance parts on them.

You can goto ar15.com and look under the 1911 tab, I have seen info on them over there. centerfiresystems.com usually have them for some good prices.

I havent personally handled one before but I have a few Colt Gold Match slides/barrels I've been looking to put onto something. So I may purchase one just so those parts arent sitting in a box.
