You must realize that the gun is not a shield and that you cannot block projectiles from other guns with it. Your protection is the fear that you might instill in a possible attacker by being able to kill him/her first. If you're fast enough. And always alert. Always suspicious of your surroundings. Always ready to unleash that preemptive strike you've been training for every week. But you're not living in fear. No sir...
