Back up gun? Do you really need a primary gun? The stats say no. The overwhelming majority of the population will never NEED a gun to stay alive. Yet, most who post on here carry at least one firearm. Why? It's the numbers that do need a gun that bother us, me included. So, the question is not, "Should you carry a gun?" as I think most on here will agree it is appropriate to carry. If that is the correct question, then the next question should be, "How many guns should a person carry?" In my mind, it is a simple answer: One more than you think you will need. In my career, that has, at times, been one. At times it has been 4, not counting the 12 ga in the trunk. Currently, it is not rare for me to have 2. Which 2 depends on the day and task at hand. I own a small gun shop, and will carry 3, in part to show my clientele how easy it is to carry more than one, and how easy it can be to conceal more than one gun. Why do I feel the need for "one more than I need". Easy. Ever had a gun fail? I have, 2 different guns, 2 different occasions. One was a S&W 66, the other was S&W 686. Both were department owned, and maintained. Both had to go to the armorer before I could go on duty.
For what it may be worth, the ones who have posted about the North American Arms, these fall into the "if I have a pocket, I have one" category. Rarely is it my primary, though.
Don't think there is a need for a back up? Don't carry one. Don't condemn those that see the need. If we as a group cannot come to a common ground on an issue this simple, how long will it take for those who see no need for a gun of any kind, (other than those carried by their bodyguards) to push for common sense gun laws, where they proclaim, "Even the gun nuts only see the need for one gun, so let's allow people to have one." You know where it will go from there. The next logical step would be, "Why one?"
