Comes a point if you want to save your life with a gun then you quit the games and study how it all works. Games are fine to build skill and dexterity with a firearm but they have little to do with reality in a gunfight. It's why the cops train with simunitions, real guns and people put into buildings and vehicles that shoot back. Games don't shoot back and it's why the most cops don't train useing game set ups.
