It's possible to do good self defense training at khsc bullseye range. You just have to improvise.
Use a sheet of letter paper as the target. It's the size of the vitals area. The cardboard within the frame (20") is about the width of a torso and arms, and about the torso height from the belt and up. Or if scaled, the cardboard at 25 yards is about the size of vitals at 10 yards.
Start from step 3 of the draw, gun rotated forward and support hand on chest. You can use a timer to time your first shots, or begin when the guy next to you shoots. Just remove about .75 seconds to account for draw steps one and two.
Another exercise. From step 3 and 25 yards, fire 5 shots with 1 second between shots. If you can keep your shots in the sheet of paper, you're doing good with the sights, grip, trigger control, and shooting positions. That means you are capable of doing great at rapid fire at closer distances.
