So I've gotten into our firearms instructor course but have a slight issue with the 25 yard support hand barricade part of the qualification course. I wasn't quite sure whether to place this in Drills and Practice so I put it here.
Besides constant dry fire practice to get the finer parts of trigger control under wraps and besides practicing firing from 25 yards support hand, are there any other methods or things that I can do to improve my support hand shots at distance?
