record AVERAGE times, ranges, etc, in a notebook. u will be AMAZED at the diff in speed that practice with such makes for hitting, along with the mods I suggested.
Guys "think" 2.5 seconds, to react, raise from low ready, and hit 10" at 50m is fast, and it IS, with a stock gun and no more efficient practice than they've had. With a modified gun, tho, and proper practice, it's a 1.5 second thing, and with an optical sight, it's 1.3 seconds.
Do you WANT to just GIVE ALL your attackers an extra 3-4 shots at you, for no reason?
