TM - I have an Ultra Crimson Carry, and love it...except for the grip is not big enough. I wanted to get a Baby Kimber to get a Kimber in all three sizes (I have a Tactical Custom and Eclipse Pro as well), but after getting it I realized that I should've stuck with the Pro Size. I have an Eclipse in that size and love the gun, and the size fits my big hands better. Small Kimber = great for carry, but not that enjoyable to shoot volume with.
I like the CT grips as well, make sure you know how to shoot without them first. Another thing to consider if you are going to be shooting a lot in addition to the models without the night sights: the Crimson Carry Models and some other Kimber models do not come with frontstrap checkering, which I prefer. I guess there is a give and a take with everything...but I would reccomend the laser grips if you think it's a good idea.
Good luck in your quest!
