Ok, I know this is a mall ninja question,. . . . kind of. If you could only carry one, whould you carry extra magazines or a Back Up Gun (BUG)? Lets assume that you can only carry one. (Like I was planning on carrying a G19 with either extra mag or two -or- a 380 kel tec to throw an example out there). My thoughts are, BUG's are usually much smaller than even a primary CC handgun. Extra mag doesn't compromise any more (than you already have) in the fire-power department. A BUG lets you have a gun even if your first one has a catastrophic failure. Opinion? Ideas?
