I don't wear "skinny pants", but any IWB Glock for ME, takes me to a pant size that looks like I'm walking around with my shorts full of, well,you know. So the Kahr gets carried the most. My wife can make it FTF, however I've yet to do so even trying.
That being said, I prefer my Glock over my Kahr IF I don't have to worry about concealing.
I carry a cw40 and a Glock 23, usually it depends on the situation.The Kahr seems a little more finicky to operate, Glocks are just easy. Both shoot well and are extremely accurate for me, like what was said before, what feels best in your hand. The Kahr will have a little more recoil IMO. I love them both, you should be able to get the Kahr considerable cheaper.
