The only time I've ever carried a BUG was in-country. M-16 primary, 1911 BUG. MHO? Unless you're an on-duty LEO or high profile security, one's enough. The average Joe/Joanne going about their daily business will, in all likelyhood, never have to draw their EDC in anger, much less run dry and have to resort to a back-up. Should the worst ever happen, the first thing the authorities will ask is, "Why two guns? You looking for trouble?" and it goes downhill from there. Like I said, it's MHO. If you want to carry a BUG, by all means, rock on.
