Remember the five rules of a gun fight:
1) gun beats no gun
The gun you left at home because it was too big, printed too much, hurt your wrist or cost too much to shoot is “no gun”. Remember this when you decide between your hand cannon and your pea shooter.
2) fast beats slow
The first to get their gun into the fight usually wins as it causes the other to take cover. Remember this when you decide how to carry as the extra second it take to get the gun into the fight might cause you to lose the fight.
3) a hit beats a miss
A .22 that hits beats a .44 mag that misses. Carry what you can shoot accurately and under stress.
4) big holes beat small holes
After taking all the above into consideration, making a big hole will often cause the opponent to bleed out faster. Remember this when choosing caliber and ammunition.
5) two holes beat one hole
Always double tap. If the situation is bad enough that one hole is needed, the second hole can only improve your odds of wining the gun fight. Remember this when considering ammo capacity and carrying extra rounds.
Also, this is very subjective. What works for you, might not work for someone else. Back in the ‘80s, I was a range officer and had a little old lady show up with her .22 revolver. That was back in my “big gun only” days but that grandma shot the eyes out of the target at 25 feet. Scary thing to witness.
Amen to that!
