Last weekend when I was at Clark Brothers siting in my EOTech there was a concealed carry class being conducted.
One of the students was shooting a Ruger LC9. She had a nice holster and it was a great pick for carry.
I heard a the question, "What is the best gun for concealed carry." The teacher said, "The gun you have with you." They discussed pros and cons of cals and features. The LC9 was held up as a very good choice because of the combination of power, size, reliability, weight and concealability.
I have the Kel-Tec P3AT in .380 now but I like the LCP!
