though that may be true, most of the time when someone who knows a lot about building guns puts a suppressor on, they compensate, and on a pistol, if the sights are blocked, they'd compensate via rised iron sights, or, since suppressors are absurdly expensive in real life, they'd use an RMR with it, just because if they have a 1000 dollar suppressor on the gun, might as well but a decently expensive optic on it.
