Actually I can't conceal carry for another 9 months. I'm only 20, my dad got me the handgun because he trusts me with it enough.
I have always loved glocks and I will probably buy one when I turn 21, either a 17 or 19. Probably the 17, though.
So far all I've seen that I'm interested in are IWB holsters. They seem more concealed. Probably at 4 or 5 O'clock.
Not sure though since I can't carry yet and haven't thought all that much into it. Even when I do get the license the gun will probably stay locked in my glove compartment. I don't usually go dangerous places, the most dangerous being campus where you can't carry a firearm anyways.
