Here is a stress and multi weapon drill we used when there was time. It is comprised of five stations with the first being a little complicated to explain, but I'll try. Don't try to picture this in your head, there is a pic at the bottom
Start at the 50 yard mark. Time starts and you RUN to station 1.
Station 1: 20 yard mark you encounter a 4x8 sheet of plywood stood on its side supported 12" off the ground. It is labeled 1 top right, 2 top middle, 3 top right, 4 bottom left and so on. Stood up 10 yards behind it is another sheet except the order is changed. 1 bottom right, 2 middle bottom, 3 bottom left and so on. Your task is to draw your side arm and shoot from 1 to 1, then 2 to 2, 3 to 3 and so on. This is where weak one handed shooting comes in. When your done, holster and run to station two.
Station 2: From a kneeling position behind the barricade shoot supported strong hand across to the two VISIBLE knockdown targets (The other two are blocked by another barricade) at 5 yards. Tactical reload and move to the opposite side of the barricade.
Station 3: From a kneeling position behind the barricade, you will now shoot the other two visible knockdown targets. Holster and run to station 4.
Station 4: Depending on what assignment you were was what you did to get to the targets and what weapon you used.
If you were SWAT or some other special assignment (high risk warrant) there was a practice door. You slung your assigned weapon that was on a rack nearby (usually a Benelli or an UMP-40). Once slung, you grabbed a one man ram, rammed the door, dropped the ram and engaged five knock down target.
If you were patrol, the door was replaced with a mock window and your gun was an 870. Same drill, but you engaged the targets through the window. When done you secured the weapon and ran to five.
Station 5: At the 50 yard mark you proned out with an AR and shot three dinger targets. When the third dinger was hit you were done. This entire drill was done in 3 minutes or less.
Oh if you were a sniper, then the rangemaster would have set you set up on a pad 100 yards back.
This was a fun course to do and this was where all the SWAT guys got put back in their place.
Below is a pic I drew up for anyone interested. Red arrows are your path and blue arrows are bullet path.
