This should confirm any doubts you have about whether things you see in movies or video games are realistic. The hits on the weak side target are unacceptable- especially at that distance. By unacceptable I also mean unsafe in any defensive situation.
The path to success in a defensive situation in the real world involves copious practice, techniques focused on repeatable accuracy and creating a stable platform for your weapon system. Also do your best to only handle one weapon at a time.
