The 5 rules of a gun fight:
1) gun beats no gun
2) a hit beats a miss
3) fast beats slow
4) big holes beat small holes
5) two holes beat one hole
Learn them and understand them. If you cant clear a jam or run out of ammo, you have no gun. A .22 that hits is worth more than the .44 mag that misses. The first one to get their gun into the fight normally wins. Larger bullet holes bleed out faster. Two bullet holes also bleed out faster.
