In 9mm, I carry (or own to be able to carry) a Glock 19, a Ruger LC9, a Kahr CM9, a Ruger SR9c, and a Springfield EMP.

My Ruger LC9 gets carried the most, and was the cheapest of the lot (other than the Glock 19, which I received for free). A hogue slip on grip helps the LC9 a lot.

My most carried CC weapon is a Ruger LCP in 380 auto. I carry big bore stuff very frequently, but my LCP is almost always in my pocket.
