Now wait a minute! Don't tell him he can't improve his skills in the next week!
Sharps, set up a good draw & dry-fire session and run it 100+ times each night before the match.
Put a dot on the wall. Get a stopwatch or timer that will beep. (Set it to 3 sec. or something.)
EMPTY YOUR GUN...FOR SURE!
At the beep, concentrate on bringing the gun up out of the holster, rotating it to point toward the target, and then bring it forward and your weak hand up to complete your grip as it's moving toward the target. Do this precisely and smoothly, exactly the same way every time. Even if you have to do it at a snail's pace. Up, rotate, forward, weak hand grip, sight on target, click. Develop a cadence or rhythm to help you do it just the same each time.
As your arms extend, make yourself see the target, and see the front sight homing in on it. Your shot should break just as your arms reach their correct extension. Make yourself see the front sight (in focus) right on the target (blurry) before, during, and after the shot break. Don't let the trigger finger movement wobble the front sight off the center of the target.
Then bring the gun back in toward your chest, reset the hammer/striker, and holster. Holster smoothly every time -- without fumbling for the holster, digging the muzzle in your side, or using your weak hand to locate it!
If you do this correctly 100 times -- as slowly as you need to go to do it very precisely, and stopping each night if you start to get sloppy -- it WILL improve your performance.
Maybe just a little for this match...but keep doing it and you'll be a machine before too many more match days come.
If you can get these things right, speed will come easily!
Good luck!
