300 BLK subs out of a pistol length barrel (say 7-9 inches) suppressed, is about as loud as a suppressed 45. It isn't quiet, but it's certainly not painful shooting without ear pro.

Advantage of a 300 BLK as stated above, is you can load up subs for 50 yards and in, or switch to super sonic rounds. It's possible to have a zero that works for both mostly well also. 300 BLK subs don't expand like a 45 JHP but they penetrate better.
