Outside of military service, have you ever fired a suppressed/silenced firearm?
I've used one on a .22 pistol. Not that it didn't sound like a BB gun already
Never fired one. In the military or out. Outside of SOF they aren't that common. And even in SOF they aren't that common!
It depends upon the circle you're in. They're increasing in popularity in the long range competition world.
They're one of those things people don't know they need until they use them.
