Suppressor for home defense?

[blades67]

Anyone have any idea roughly how loud a supressed subsonic 147 Gr 9mm round would be?

Yes, but I couldn't tell you exactly how many decibels it is, maybe about 25 to 30.

Consider:
A 9mm or 45 "round" that's the size of a 12 ga shotgun shell BUT the round incorportes the sound deadening component(s). Possibly it would be the same length as a 12 ga shell but possibly longer.
The shotgun is not modified in anyway, shape or form.

Has anyone tried one of those barrel insert thingamajiggs that lets you shoot a pistol cartridge that chambers in a "shotshell"? I would guess the shotgun barrel would act as a "suppressor" even whithout any sinister "components". It won't be silent but the open, unmodified shotgun barrel ought to provide a long, nice expansion chamber so that the powder gases cool down and the pressure drops before the gas reaches the muzzle. More or less the same thing that happens when you use a small charge of fast powder in a long barrel, as described above by 444.

30 dB is waaaaay quiet. Think whisper or a light breeze through a tree.
