If you've mil carried for a long time then you probably will not be too concerned over concealed carry. Seek advice hear if you need a concealment holster, however. We may be able to save you from having a drawer of useless holsters...maybe! I think everything has been mentioned, other than this, KNOW THE LAW. Whether you conceal or open carry its a good thing to know the laws pertaining to both really well. You will most likely at some point be called out on those laws or harrassed about it. Being able to defend your actions helps a bunch. I also suggest maybe carrying the pertaining statutes with you if needed. Otherwise, carry often and enjoy. Welcome to full on full charged enjoyment of your rights!!!!
