Spray rounds with a semi auto? Never seen that. Still come out one at a time, as fast as you can pull the trigger. The mags (not clips) cycle rounds slower than a quick finger and a revolver do. see this Much faster than a glock 19 and walther p22 (read that those were the guns used)
The big lie here , is that during the Klinton ban, it only prohibited new manufacture of high cap mags and semi-autos. It never banned the possession, buying, or selling of hi-cap mags or semi-auto weapons with the “evil” look .
