I took a 3 day trip with my wife and daughters and carried for the first time. I recently received my permit and this was the first real test. I carried a Ruger LCP in a Galco Stow-n-Go IWB holster. I carry in the Appendix position. The whole rig was very small and light. It concealed well with shorts and a t-shirt. At first, I was a little self conscious, thinking everyone was looking or would notice a bulge. But, when I looked down even I couldn't see it! No one gave me a second look.
Next I'll try my Kahr PM9 and then my S&W 642. Both are a little bigger than the LCP.
