I don't have my concealed carry permit. I was thinking about attending a class this weekend, but my son asked me to wait until he could go with me. He plans to carry his Colt Delta Elite 10mm. He also has a double stack Taurus PT-111 9mm that is really fairly small, but holds 12 rounds.
My choice will likely be a smaller Ruger LC9 or Springfield XDS 9mm. I might try the S&W 1911, but I suspect it will be too big. My son is bigger than me and has more room to hide his.
