You can do a lot at the range with only a little setup and some creativity. Here's a setup that I use a lot, and we'll take a look at some drill options. These drills can also be set up to run with your SIRT for dry fire skill building, as well as integrating the SIRT into repetitions with live fire (alternate running the drills with SIRT and then live fire runs).
Use 3 targets, spaced roughly 6 feet center to center. The targets can be either IDPA or USPSA targets, or whatever you like. The shooting boxes can be cones or even just some marks on the ground, it is not that critical. Firing lines are set up at 7 yards and 12 yards.
The first drill set is pretty straight forward, and emphasizes target to target transitions and the draw. The shooter's position is purposely set off center, as we tend to get too comfortable being centered on a target array when we set up drills at the range. All starts are hands at sides, but you can substitute whatever start position you want to work on.
String 1: Starting in Box A. Draw & fire 2 on each body, T1-T3.
String 2: Starting in Box A. Draw & fire 1 on each head, T1-T3.
String 3: Starting in Box A. Draw & fire 2 on each body, T1-T3, then 1 on each head T3-T1.
String 4: Starting in Box B. Draw & fire 2 on each body, T3-T1.
String 5: Starting in Box B. Draw & fire 1 on each head, T3-T1.
String 6: Starting in Box B. Draw & fire 2 on each body, T3-T1, then 1 on each head T1-T3.
Try to set the drill up similarly each time you run it, and record your scores and times. You should look for times that allow you to shoot all A/-0 hits on the body and A/B or -0 on the head.
