I have the Colts more for investment than anything. I can't see putting $$$$ into them. I prefer the Glocks to the Colts. I know, I know heresy I know. 
I don't think is heresy at all.  Some 1911's can be temperental and quite expensive to "get running".  I have been lucky I guess with my 1911's, but I have not had to put a single cent in to my Glocks, they work right out of the box, no questions asked.  They are both great tools.
