Any opinions on which of the following measures up better than the others. I like what I've read about the Kahr. Want a Light and THIN CCW.
1) Kahr P9 or PM9
2) Walther PPS
3) Taurus PT709
4) Glock 26
5) Kel-Tec PF-9
6) Other???
Of the guns you listed, I would go with either one of the Kahrs. The G26 is a great gun but definitely does not fit the thin requirement.
I know you said you prefer a 9mm, but have you considered an S&W Airweight revolver? Very light, very thin except for the cylinder, easy to conceal, .38+P is a very adequate round, and more reliable than any semi-auto. You do give up a little on capacity. My main CCW is a S&W 642 and it works very well for me.
