I'd be cautious in considering a backback to be an "opaque case or wrapper", without the gun case. You're probably correct, but I'd use the case anyway, just to be safe. However, that would mean that if I was 18, I could carry a gun in a reachable side pouch in my backback, and a magazine in a mag holder, or something, and effectively CC, with about an aditional 3-5 seconds to draw and charge the weapon over a regular CCer.
18-20 can also have an unloaded handgun in their car, so long as it is out of sight and the car is locked when they aren't in the car.
EDIT:
Also, would this be considered an "opaque case"? If the 18-20 year old were to wear this holster with the magazine in the pouch, and the pistol unloaded, would it be considered legal?
