Deadly quiet!
On my wee Martini you could aim at a target, fire the shot, and only hear a faint 'click' from the firing pin, then nothing until a 'thump' from the target showed you hit it (sighted in on a gum tree I didn't like).
I don't see how anyone can't make them that quiet these days.
Is it the metal can allowing the noise to come through?
I have a modern screw-on .22 suppressor that is meant to be an OK NZ made one (stuck it on my JW15), and it's way noisier than my plastic jobby (and yes...same ammo used).

I've made many ally and ally/carbon fiber cans but the 3D printed ones I've started using are much quieter, not sure how long they'll last though. It could be the fact the plastic is more porous/sound deadening.
