Isn't the Castor Troy rig backwards from what a small of the back holster configuration should be? It looks like when you draw, it might be likely to sweep your body.
My understanding was that small of the back holster, for drawing with the right hand, faces the same way a right hand hip holster would sit, just rotated around your waist to the small of your back.
I couple years ago I had a matched pair of Colt 1911s. Put together a double shoulder rig from some used Galco outfits. Just the guns, no extra mags. Was kind of cool for a while, but I found it uncomfortable for long term wear.
If you can conceal them comfortablly, I can't see why not. Can a bad guy crap his pants twice in one draw of such formadble 45s?...Personally, I'd rather carry my Kel-Tec P-11 9mm (12 +1) CC IWB, a good boot knife in my boot, and LEO strength pepper spray in my pocket/on belt. Maybe an expandable baton just in case (or is that too much?)
