Tap, Rack, Bang.
Getting to the BUG takes longer than it'll take the BG to move the thirty feet if'n he's already in motion and I have to recover from the shock of the "Click!" Those clicks just don't come from my carry gun and it'd take me a second to drop back to a course of action different form the normal training I've done to counter them...
And of course pistol whipping takes place if he beats me to it -
Tap, Rack, Whip, Whip, Whip, Bang!
