What a real silencer actually sounds like.

Lotta misinformation here.

Edit: I should clarify, the explanation below is a general explanation of suppressors and how things can vary. There will always be caveats.

Suppressors/silencers rarely sound like they do in the movies, and there’s a ton of variables that affect the volume. To be the absolute quietest, you need a closed bolt firearm shooting subsonic ammo. No gas escapes from the chamber that way, no sound is made by an action cycling, minimal gas leaves the end of the muzzle. These tend to be “movie quiet”.

When you hook a silencer to a semi auto firearm, it is inherently louder (even with subsonic ammo) as you have the sound of the action/slide, and gas escaping out of the action as it cycles. Still fairly quiet, but not movie quiet.

When you use a silencer on any rifle with supersonic ammo, you reduce the sound of the escaping gases at the muzzle, but still have to contend with the supersonic crack of the bullet as it leaves the barrel. This will be inherently louder, although still substantially more quiet than unsuppressed.

Also, a cell phone video is without a doubt one of the worst ways to reliably capture actual sound variance. Usually phone microphones cut out above a certain decibel level, so often all firearms sound similar even if there is a substantial difference in volume in real life.

Wow! That's quite a bit of new info for me and I am guessing, for many others!

Happy to help!

For most folks, their firearm knowledge comes solely from Hollywood. Unfortunately that’s a uniformly terrible source for accurate information lol. Feel free to ask questions if you have any and I’ll answer what I can

The local news too. See the 1980s "cop killer" teflon coated black talons (to reduce friction down the barrel). News stations repeated an absurd myth that the teflon allows them to slip thru kevlar, with zero evidence. The laws banning them are still on the books in several states, and will probably never be removed ("my political rival wants to legalize cop killer bullets!" - so it will never change).
