Thanks for the input, Mike. People sometimes hate hearing that there is no "easy answer".
It is probably also worth mentioning something that happened on the range on Wednesday:
I had a student who was using The Urinal Position as his "ready position" (gun held in front of crotch, arms extended, gun pointing down). When I explained the High Compressed Ready and the advantages I see in it, he started shooting from that position. A little later, we went to presentation from the holster. We integrate the startle response into our draw, so it starts with the hands coming up towards the line of sight and in front of the body (protectively, simulating the instinctive flinch that occurs in an ambush). After doing this, he then left his weak hand out in front of his chest when he went to grip the pistol and it ended up in a position that pretty much had it being covered by the muzzle 75% of the time after the gun was oriented towards the thread (at the side) and extended out to a shooting position. Obviously, this bad. I think this is one of the reasons you see most CFS students bringing the support hand in. When we train for contact shooting, one of our premises is that you are probably already in contact with the attacker, so the weak hand position is not going to be choreographed, but dictated by the nature of the fight.
