As opposed to the ancient art of Gun Fu (some call it Chi-Ching).
Of course, Chi-Ching is merely a modern - although powerful - variation on the ancient Chinese art of Gun-Fu. It is said that Gun-Fu masters can kill a man by merely pointing at him. Some of them can kill their opponents from as far away as a kilometer or even a mile. Now that's a powerful chi! Many different styles of Gun-Fu are practiced throughout the world, including .45ACP, .357mag, .44mag, and 5.56mmNATO. Mixing styles is considered very dangerous to the practitioner, except in special cases (i.e., 5.56NATO and .223).
