In a Western: Stand upright facing your opponent, arms casually dropped on the sides, with elbows slightly bent outwards. Gaze at your opponent intensely. As soon as your opponent breaks down under your gaze and attempts to draw his gun, reach for your pistol and yank it out of the dust-caked holster. Spin the pistol three times around your index finger, and fire. Your opponent will slowly collapse to the sandy ground with his gun in his hand. Blow the smoke from the barrel of your pistol, and bow to the fair lady with golden curls who has witnessed the incidence calmly on the nearby terrace. Spin the pistol three times around your index finger and in one unbroken motion thrust it back into the holster. Walk up to the lady and offer to buy her a drink.
In a Schwartzenegger movie: Grip the bad guy by his collar, cock the pistol and point it at his head. Ask who he works for and where the hostage is. Having obtained the information, say "Hasta la vista baby", release the bad guy and he will fall down to the street from the roof-top of a fifty-story building. Pocket the pistol and tidy up your suit.
In self-defense: Usually you will be panicking in face of the approaching assailant, so try best to steady your hands. Take the pistol out of your pocket, grope for the safety slide and push it downward to free the hammer. Should you drop the gun in the course of this action, pick it up and repeat. Should you complete this action before the assailant wrestles the gun away from you, point the gun at the assailant and continue pulling the trigger until the magazine is empty or the barrel is jammed, whichever comes first. Check if any of your bullets has disabled the assailant. If not, scream and run away as fast as you can.
In a paroxysm of anger: Take out the pistol, cock the hammer, and aim at your object of anger. Threaten the person and demand an apology. Your request may be denied, which will fuel your anger even more. If a rush of blood to your head impairs your judgment, that is, if you lose your head, pull the trigger. You have killed your victim. Say to yourself: the person is dead.
And repeat: the person is dead.
