in the past, but you never know when this mechanical contraption will break down. As a result, having a backup gun is more than a luxury—it is a necessity.
The first decision will be what to select: revolver or semi-automatic? I personally prefer pistols, but a revolver is a very viable personal security firearm. The primary reasons most will select a pistol will be ammunition capacity and a slim profile, which are definite advantages. But once you decide on a pistol, which model do you buy? When it comes to firearms, size matters. You want a backup gun to be a “handful,” a gun that is small enough to conceal and carry without unreasonable effort (effort will always be required), but large enough to fill your hand and powerful enough to use in a fight.
This is a tall order when you stop to think about it. These days I find that a single-column 9mm pistol might very well be the optimal choice. When loaded with street-proven ammunition, the 9mm can be an effective fight stopper as long as I do my part, and with a capacity of seven to nine rounds and the ability to quickly reload, I should be able to handle all but the most extreme circumstances.
