Many years ago when I was one of the scout leaders we had a local police officer visit a troop meeting. The boys seemed to think the bigger the weapon the better. He showed them you only needed slightly more force than the perp and demonstrated several one hand and one finger holds. When the boys asked about drawing his gun he replied the same as Johno02 posted above, "I only pull my weapon if I intend to use it and that would be if my or your life were in danger". Over the years he proved that true in some very tight situations where his cool head prevailed.
