It's news to most people, cause they aint tried it. NOBODY can match the speed of a hand in pocket draw, using a concealed belt rig, with the hands starting in a discrete position. You give up at least 1/4 second, time for EACH enemy to shoot stab or club you, with EACH hand. Most people are giving up 1/2 second or more, too. If you can't see trouble coming in time to put your hand into your pocket and on th gun butt, no gun or rig is likely to save you. Pull that gun "too soon', and you'll get a brandishing charge and loss your ccw permit. The hand in pocket lets you wait that last "extra" fraction of a second, before declaring yourself. By far the great majority of the time, you don't have to fire, IF you get your gun "on" the miscreant in time for him to see it and stop his attack. Many more times, MISSES suffice to run him off, or fast, solid hits with a "mere" . 22lr suffice, too. It's actually quite rare for a civilian to have to "shoot him into the ground" with solid, powerful, swift repeat hits. That is, IF you are smart enough to leave him an escape route. It's even more rare for you to have to hit more than one attacker to run off his buddies.
