You don't need to suppress the noise as much as a silencer.
A person might want to know that his gun was fired -- such as a child firing the handgun.
That was my point. Just something to allow a person to hear after the gun is fired. A silencer would be okay, but knowing a gun is fired might be a desirable thing (as I pointed out above).
A gunowner would be horrified to find a child/person dead because he did not hear the shot of his gun from someone playing with it. And if it has a 'distinctive' sound, the homeowner would know it is his gun being fired...
That is the 'why' for my point of view (which could be total nonsense).
Suppressors do not make a gun silent nor do they actually suppress the noise that much in the first place. You still get the sonic boom of the supersonic projectile (unless you’re firing .45ACP or other subsonic ammo) and the surprisingly loud sound of the firearm’s action. Suppressors do not silence a gun; “silencers” is a bit of media conflation to make it seem like a product only used by criminals and has been since before 1934.
Your point of view is sadly total nonsense.
Your notion of what a ‘silencer’ does seems to have been formed by Hollywood. As others have indicated, that is a false notion. In fact, it is the very same false notion that led an ignorant Congress to make ‘silencers’ practically illegal in 1934.
I doubt you have ever heard a suppressed fire arm. They are not silenced like the movies pretend. In fact unless you are a regular with firearms you probably wouldn't even notice a suppresses firearm was "Silenced."
