1. As long as you have the "SA" license, you can literally carry ANY pistol....right???
Example: A AR-15 pistol .223 cal. with a beta-mag. Yes, I understand that this is not only extremely impractical, but hard to conceal, more of a theoretical question rather than pragmatic.
Do class III weapons (again, not asking practicality,rather legality) count as valid carry weapons?
2. At what point would one NOT need to disclose (legally) that they are carrying when pulled over
Say I had ONE (literally ONE) beer at a bar, and beforehand I unloaded and locked my gun away--in my trunk-- and on the home trip, get pulled over, I'd have the gun in one of these, in my trunk:

YES,I understand the preferred "safe"method would be leave the rig at home. Would I need to announce even though I am not in reach or proximity, to a locked, unloaded weapon? If so, how does the officer safety requirement for disarming and inspection come in to play given the impossibility of its' use?
If so, what if I bought a stripped lower-receiver that literally was just a block of metal in the car? What is the requisite for disclosure?
3.I haven't seen many of you talk about the Taurus Public Defender revolver. I know it can take .45Long and .410, but because of the barrel it is still considered "carryable" with a CHL, right?
Why haven't I seen anyone on here carry one? They have a small polymer framed version now, if weight was the limiting factor. I'm partial to Glocks,1911's and pocket guns like many of you, but I really enjoyed the feel of one at the gun show. What am I missing here?
Thanks.
