Maybe I can help. Mine came with CT grips. Just for reference, I bought my K6S just as they came out with Lasergrips. I paid delivered and transferred just over a grant total. At that time the gun with rubber grips was selling on GB for $750 and up.
1. I am a huge believer in CT laser grips and I can write novels as to why they are on all my carry revolvers.
2. The CT lasergrips on the Kimber are from their master series and they are very well thought out. The
slatewood and rubber combo is comfortable, compact, and does not get hung up on clothing.
3. I own a 640Pro with a set of LG350's green and the rest are all red. In no way would I ever spend the extra money for a set of green again. They do project better and they are visible in bright daylight but I consider my snubbies to be up close and personal firearms and because I can better see a green dot at 50 yds in bright sunlight does not mean I will take that shoot with a 2" gun.
4. I just returned from the range today wishing the Kimber's lasergrips were a bit fatter toward the base. Don't get me wrong the combination of wood and rubber is a great feeling product, I just have big hands and to get my finger correctly on the trigger I need to grip that gun lower rather than the preferred high grip. I do not have a set of stock rubber Kimber grips to compare but I would love to see set of Spegels boot grips just for feel. I am thinking of wrapping a couple of turns of
tourna grip tape around the lower half but I don't have much room without activating the laser grip on/off button.
5. $370 is a lot unless you have the cash to spare. If the K6S is your SD gun and you are a lover of lasers go for it, if not, you may wait until there are more grip options out there with better feedback than I can give.
