I was in the same boat as you....looking for a slim 9mm for CC. I did plenty of searching and finally decided to put an SR9c on order. Yes, it is wider that I was planning on, and I probably would have rather had something more in the Kel-tec size range, but I just can not bring myself to buy a DAO gun. I've handled several, including the Kel tec's and Kahrs, but a long, heavy DAO trigger is just not working for me in any type of gun. I picked up an SR9c at a local dealer and was very impressed with the trigger on it.....very light and not much travel. That, along with the added mag capacity, convinced me I could learn to live with a bit "fatter" gun.
I would suggest taking a trip to the local gun store and trying the trigger pull on the Kel tec before making any hasty decisions.
