“unless you have at least a level 2 holster”
While I myself have a concealed carry permit here (Arizona), I do not use a holster because I sit in a wheelchair all the time. Just ‘cause I am curious, what exactly is a “level 2” holster?
Short answer: a holster that it's hard to get a gun out of from which -heh heh- unless you know how it works. When I was a depiddy I had a level 3 holster. There are level 4 holsters.
