It's as thunderous as a shotgun, that's for sure! Sounds more like a loud machine gun that gets quieter as it's being discharged.
Definitely not something I'd want to have pointed at me and fired. It sounds like it'd blow you apart without any trouble. Hopefully this guy's drawers managed to survive such a malicious assault!
Loud and forceful, just like a shotgun! Not overly beefy but still has some grease. 7/10
