Most of that stuff isn't worth the powder to blow it to Hell.
I have a Kramer deep cover T shirt for those times when you absolutely, positively don't want to be "made". But even though it fits the torso tightly, and a 342PD filled with 158's weighs as little as a handgun can, you still find yourself wishing you'd bought two guns, so the downward pull would at least be even on both sides of the ambi pockets. Wearing even a medium weight gun on only 1 side would be like having your "package" pooching half way out of only one leg hole of your tighty whities.
But if the circumstances demand it, you "does what's you got's to does"! And are damned glad when your done doing it, you don't have to do it too often?
