Nice gun. I have one and shot it next to my Kimber ultra carry II and the Sig is a tick nicer IMO plus I don't like how the ultra carry takes down.
The one thing I can say for the Kimber ultra carry II is that it has a pretty good reputation for running very dependably. So far my sig is 100%, but it's only got 100 or so and the Kimber has 200-300. Both are very nice IMO.
+1 on the G36 tracker.
As for cocked and locked... I am very conscious of my side arm when carrying cocked and locked and I like to forget I'm carrying, but as others have stated its the only way to carry a 1911. That's why I don't carry mine typically.
