9mm Suppressor that can handle 223 pressure.

[KAK]

I was wondering if anyone knows of a suprpressor that is crosscompatable between 9mm and 223. I know the threads are the same on lots of guns.

I know the 9mm size suppressor wont suppress a 223 as well as a 223 suppressor.

I don't think there is one. You would have to make a custom can made out of the appropriate materials. Even then your suppression level would not be good.
The levels of pressure at the end of a .223 barrel would blow any aluminum can apart. Even if you made a can capable of both I bet the sound would suck on a .223 and your pistol would be so front heavy you would probably want a stock to shoot it.
