I carried a M & P 9mm daily owb for several years and then switched to a Ruger LCP 380 when I stopped working in the field and took on an office job. My favorite gun is probably a Springfield Armory XDM 40. I like the way if fits in my hand, similar to my M & P.
I have never liked Glocks, sure they are great and they have a great warranty and they are local, but the grip is not right for me. I am not sure if its the angle or the grip molding but I was never able to find one that fit right.
