Welcome to TFL, David spargenator!
When I first spotted this thread, I think it had one response and I seriously considered deleting it. The Firing Line strives to be "a virtual community dedicated to the discussion and advancement of responsible firearms ownership." When someone starts a thread and states that they want to carry X, Y, or Z because it would be "cool," or "badass," then (as you have seen) some of us have some reservations about the thought process that went into selecting X, Y or Z, and some reservations about whether doing so is responsible.
Shotguns are cool, no doubt. I'm rather fond of them. In their own ways, handguns and rifles are cool, too. I've brought some targets to spectacular ends using them. However, your choice of CCW really shouldn't be based on the cool factor. When you choose your CCW, you are choosing to carry a weapon that could, on very short notice, be called upon to end another human life. Should you ever have to do that, several processes may well be set in motion that are anything but cool.
Now, with all of that said, it looks like we've had an answer or two that are actually responsive to the original question, and this thread otherwise has been more about the advisability of selecting a CCW for its cool factor.
Again, David spargenator, welcome to TFL. I'm going to close this thread, as I think it has served its purpose now.
