Caught this in the 1996 Guns & Ammo HANDGUNS Annual.  Article titled:
OUT OF THE BOX, ONTO THE RANGE What to do after you buy your gun by
Gerald Brennan.
BEGIN QUOTE ***********************************************************
. . . An acquaintance of mine in a law-enforcement reserve unit nearly
killed a man once because of poor training techniques that he practiced
on his own most zealously.  He would be at the range at least once a
week, amd his drill consisted of whipping his gun from the holster,
snicking off the safety and firing.  No one was more impressed than he
was with his lightning-smooth draw and impressive accuracy at combat
distances.  Recently, he was obliged for the first time to quickly
unholster his weapon in the line of duty.  He snicked off the safety and
had a flash of terrible confusion as his muscle memory told him to pull
the trigger though the situation didn't warrant this action.
His old "fast draw, safety off and shoot" method is now combined with
a new drill that eliminates the reflex shot and places him at the ready.
He has added to his practice sessions a third drill that incorporates
the go/no go decision at the point of target acquisition.
