Since most armed encounters don't even require the gun to be shot(J.LOTT), you can save money by carrying a realistic looking rubber pistol
There are plenty of docmented cased of a single bad guy taking 6 or more rounds and still being able to fight.
So the idea that "one round for each bad guy" is going to git-r-done seems optimistic at best
For many people the idea that each round will score a good solid hit is optimistic
Like all these discussions...what gun, what caliber, how many guns is a personal choice (generally related to comfort
)
Just please make it an informed one
And notice....most anyone that teaches
fighting with the handgun (rather than just shooting) advocates a semi for your primary weapon
