New to the forum guys I need some help trying to purchase my first CC gun. My state OK is open carry but I would like to conceal still. I am 5'6 140 so I'm a small guy so I don't need a hand cannon. I am down to a 9 or 40. I have looked at HK, SW MP, Glock, Ruger everything I need some help. Everyone seems to have a Glock but why? They seem bulky to me. Just need some general help.
