I'll have to echo the CS-9 as my favorite S&W auto. Light and compact enough for ISW carry. Big enough with the stock Hogue grips for comfortable shooting. Easily accurate enough for it's self defense role.

I do have two more to choose from that also get very high marks for their particular niche, a 1006, and my most recent acquisition a 1076.

10mm is my choice if things would ever get serious and I will carry the 1076 if the situation allows. The 1006 is a range gun and a joy to shoot.

But for me, it's love the one that's with you.
