Do they all get suppressed equally ?
Or
Do some get suppressed much better than others ?

And do carbines and hand guns
Differ greatly
in amounts of suppression..

If the job that needs to be done,
Can be done with either, ( using a suppressor )
Is there an advantage to
using one over the other ?

22’s are able to be effectively suppressed to Hollywood quiet.
The heavier the bullet= the better suppression.
Subsonic suppresses better than supersonic. So, 147 9mm suppresses better than 115 or 124.
