Man, I really like this one as is. Almost hate to send it off... Yeah right! But, it does have a great trigger and the feel of the ambi is so nice, I'm half way tempted to leave it instead of swapping to a single side. Very positive in both on and off positions. VZ grips feel really good in the hand too. Previous owner used in a gun class without any issues. Really nice Kimber. Here's a couple of pics when I picked it up.
