I can definitely see the advantages, but to a regular Joe like me I don't really feel the need to carry a backup gun. Unless someone felt uncertain that their primary was not going to function properly. Then I would say get a different primary,, I would not carry a weapon if I was not 100 percent sure it was going to work the one in a million time that should need it. But bugs seem to just be more weight,, Holster adjustments,, etc.. Wondering how many actually do? And are they situation specific, or just going around every day carrying?
