Tueller drill proves that a gun in the holster for even an individual who is competant enough to draw a pistol and shoot some what quickly is well over 21 feet of distance. that means if somebody is attacking you with a knife from a minimum distance of 21. Staying motionless and trying to draw your gun from a holster position and dispatching a threat before you are cut, or killed is impossible. Remember most people who go into a survival mode rely on gross motor skills and the mind can really only accomoplish one thing at a time. Draw a gun or Move, most people don't know to both when its the first time getting shot at.
Most human beings run the 40 meter dash in about 5-6 seconds.
40 meters=est 120 feet.I'm not even adding in the xtra 3 inches or whatever.
So somebody who is running the 40 meter dash is averaging 24 feet per second. Thats distance crossed.
The average person who carries a gun takes about 1.5 seconds to get the gun out of the holster and fire 1 shot unaimed, from a holster that has 0 retention.
Now add stress and most police don't talk to people standing 24 feet away. They do it at conversation distance 5-6 feet. This distance doesn't come close to being the MINIMUM safe distance from standing with somebody holding a sharpened pencil. Not to mention most cops carry level 2 retention systems I think some are carrying Level 3. Which is absurd if you think about it. Now if the cops wearing a rain jacket or a overcoat adds even more time to his already limited draw. Again we are talking only about 1 shot from a pistols. If you read Cooper or Ayoob, Applegate, etc.... They all say that there is no Pistol, that is a good comprimise to carry adequate to stop a Man with one shot. So why not give them the appropriate tool/ equipment to due the job?
