Five rules of a gun fight:
#1 - gun beats no gun
If you cant clear a jam, you have no gun
#2 - fast beats slow
He who shots first forces the other guy to take cover
#3 - a hit beats a miss
The .22 that hits is worth a whole lot more than the .44 mag that misses
#4 - Big holes beat little holes
Subject to 1, 2, and 3 carry the biggest hole maker that you can shoot accurately
#5 - Many holes beat one hole
Anything worth shooting once is worth shooting twice.
