My plan was to carry an AK-47 pistol hung from a single point rig in a SHTF situation. The firepower offered by that pistol is hard to duplicate and the AK pistol lacks that goofy spring tube at the rear of the AR pistol.
I got the gun and the rig all fixed up until a friend advised me of the shoulder holster/belt holster OC rule. Well, Hell!
Tried to find a workable solution to still be legal and gave up on the concept. I settled on shoulder holster rigs for 9mm, .40 S&W and .45 acp full size pistols, instead. Those rigs have provisions for two extra magazines which gives a combined total of 50 rounds onboard. It's unlikely that I'll ever need more than that!

If this was the case, rules wouldn't apply I don't figure....
