The statement made that a backup carried by a civilian is ridiculus is a bit short-sighted given that the people making the comment are not aware of the circumstances where people have felt it necessary to carry a backup. There are a variety of civilians who need to carry if they need to carry, then need to consider a backup as well. As a merchant, it is certainly a good idea (based on previous experiences). As far as the reasons I find it necessary now, nobody needs to know. Personally, I never thought I would be carrying in the first place, but at times I do carry a primary and a secondary or backup gun. Since my primary is located on my strong side, my backup is placed on my weak side for weak side access. I practice drawing and firing weak side and one handed. My backup is a Colt Pony loaded with hydrashoks. Proficiency with your backup in the configuration you carry it is just as important as proficiency with your primary gun.
