Tips and Tricks

 * If you are close to an enemy that hasn't seen you yet like in the mission On Shaky's Ground when you enter the warehouse the first enemy won't have seen you, switch to expert targeting and shoot him in the head, then switch back your preferred targeting.
 * In addition, Dead Eye can be used to acquire this achievement, making it much easier to get.
 * You can get this easily by taking up a nightwatch job and shooting a unsuspecting Robber/Brawler/Stealer/Or Kidnapper in the head with Dead-Eye.
 * Another easy way to get this is to go to the Armadillo saloon and shoot a waltons gang member.
 * It has to be an enemy.

Trivia

 * Strange translation from GS to trophies, as for most games a 5g achievement would be worth a bronze trophy.
 * Almost any weapon can be used for this excluding the Knife, Fists, Lasso and throwing weapons like Fire Bottles.
