i got the pro cdp and it was worth every penny and c notes..
it is my favorite weapon that i own. and i have wilson mags for it as well. the kimber mag jams on the last round quite a bit so i quit using that one.
i even recently shot a wilson combat full size all steal and the conclusion that i came to was the wilson was very nice smooth and heavy. like a caddy. and the kimber is more like a sports car with all the horse power. a little more fun too. didnt really shoot better with one than the other. so i do not think that it would have been worse the extra $1k and was even happier with the purchase of the kimber.
