since he can punch you in .20 second, or kick you in .30 second, I suggest that you JUMP OR WALK back as you draw, from such a close range, or that you "swarm" him with hand to hand techniques as you move forward. Cause the fastest ccw belt rig wont be fast enough, no matter who you are, if he makes a move on you at such a distance. It will take you .70 second to react, draw from a front pants pocket rig (even if your has ON the gun) and fire a hip shot, and that's still 2-3x too slow, if he suddenly moves on you. You need at least 6 ft of space, if you are hand on the gun, and more like 10 ft if your gun is in a ccw belt rig, no matter how fast you are. The guy can be all over you in 1/2 second from 6 ft, by diving at you, and in 1.0 second flat from 10 ft. In 3 seconds, he can charge and stab you from THIRTY feet away, standing start.
