Marlin camp 9 suppressor specs

Hi all,

I have just picked up a nice condition camp 9 and i'm toying with the idea of a full overbarrel suppressor. I have seen it done to a few camps but mostly .45's.

Any reason why it wouldn't be good on a 9?

Also does anyone have any spec on what size and number of ports they put in the barrell?

Thanks in advance!

The 9mm will be probably be louder than the .45 due to the velocity being over the speed of sound.
Especially since the longer barrel of the carbine pushes the 9mm much faster than the .45, out of the same length barrel.
Just something to consider.
 
Often times, when you have an integral suppressor, the actual barrel (inside the suppressor) is far shorter than the full length of the suppressor. In other words the rifle may appear to have a heavy 20" barrel. But the actual barrel length is 10" (or whatever).
The point being, that these barrels are designed to not allow a given ammo to go supersonic. I have a M-169 AR15/9mm upper that was designed to shoot common Wal-Mart 115 grain bulk packed ammo at subsonic velocities.

FWIW: my experience with suppressors in general is that the small hole is quieter. I am no suppressor expert and am basing this primarily on two suppressors that I own. One 9mm and one in .45 ACP. This is flawed comparison since the two suppressors are manufactured by different companies, the guns are different............ But, when using sub-sonic ammo, the 9mm can is significantly quieter than the .45 can. They arn't even close.
 
That's interesting, thanks. I was planning on porting the barrel to some degree but if i shortened the barrel instead and fitted a longer suppressor that might be the way to go.
What do you think is a good ratio? Barrel to suppressor?
