No cons here.
My Custom II is the best handgun I have ever owned, I use if for everything. If I were allowed to I would carry it to war. My friends loved it so much most of them switched to 1911s, many of them to Kimber. None of us has ever had any significant problem with them. If MIM parts are destined to break, all of mine must be defective.
There ae a lot of Kimber haters in here. I have responded to them, many times, that Kimber makes several TIMES as many 1911s as their nearest competitor. People who have BAD experiences complain louder and more often on the internet than people who buy something and like it. This means that a higher NUMBER of them will have problems reported on the internet. None of this means that Kimbers have a higher RATE of problems than any other manufacturer.
I have shot Baers, Wilsons, etc. I had a Nighthawk jam up on me at a rental range. All machines fail eventually. But I have absolutely no idea what these high-end pistols are supposed to do for more then THREE TIMES the price of my Kimber.
