I have a LC9 and LCP. The LCP is very easy to pocket carry. The LC9 can be pocket carried with the right clothes. I use a Nemesis holster with the LC9 and it works well with cargo pants/shorts front or back pocket.
Both of these pistols have been perfect from day one. I have 800+ rounds through the LC9 and it is very accurate. The trigger takes a little getting used to ... Similar to a revolver.
I've been thinking about a Kahr PM9/CM9 and really like the size, but am concerned with reliability reports. I may take a chance ... I just wish Kahr offered better customer support more along the lines of Ruger and S&W. I don't think a customer should have to cover shipping costs for a defective product.
