gun, in pocket. Both of you face targets, you have your gun ready to fire, pointed at your target. if his hand comes out of pocket with a gun in it, SEE if you can beat him to the shot. You can't, if he's got any speed at all. of course, to prevent your cheating, he must many times NOT have the gun, and if you fire, you were cheating, firing without having seen-recognized the threat in his hand.
