I call my suppressors silencers. This is because the word silencer is a legal term in the USA that covers all devices used on the muzzle of the firearm intended to reduce the noise by any amount. It also eliminates any confusion in that no one is going to think I am talking about a flash suppressor.
I also say the firearm is suppressed, not silenced. It kind of bugs me when I hear someone brag about how "noiseless" their guns are when used with a silencer. They must be hard of hearing if they are speaking of a center fire rifle.
