My KHSC 25 yard training routine to get familiar with red dots is do at least 10 of each.
1. Low ready. Bring the gun up from the low ready and fire a shot on target. Start slow and speed up. Goal is to bring the dot on target without having to adjust and keeping shots on a sheet of paper.
2. Compressed ready. This is to practice getting the dot on target from a draw I'll start out at the compressed ready, two hand grip just infront of my chest, then punch out and shoot. Goal is to press the trigger right at arm extension. Start slow and speed up. My goal is to go only as fast as I can keep all shots on a sheet of paper. Other things to try is fire two shots instead of one. Also start out with both hands separated on the table with the gun in one hand.
3. Rapid fire. I'll rapid fire 5 shots to practice tracking the dot and keeping it on target. Start out 2 seconds between shoots starting with two shots, then increase to three shots, then four, then five. Then speed up the cadence to 1.5 seconds then one second between shots. Again go only as fast as you can keep the shots on a sheet of paper.
Once you get pretty good at it, do it one handed, strong and support side
