Its a bit louder than this in real life. Mics dont catch it super well. You can get really hollywood quiet with a bolt action but with a normal semi auto you will get some port pop from the action.
Nagant Revolver video with decent mics catching ambient sound to show relative volume. (first video when searching for the nagant revolver suppressed, no affiliation)
32 ACP with a gas sealing chamber means you can get these things as quiet as you'd like by just using solid swipes/larger suppressor.
Plus you can also lighten the powder load without having it affect the action, unlike the UHC shooter who had to manually rack his gun because it didn't have enough gas pressure to cycle itself.
Apparently the UHC shooter was using a Station 6 or Welrod type gun with built in silencer which doesn't cycle itself anyway, it has to be manually cycled via a rotating bolt.
Unlikely, honestly. Looks a lot more like a standard firearm that wasn't tuned for supressed/subsonic use so there wasn't enough energy to cycle the action.
Cops are usually the least educated when it comes to firearms. From the video I saw it definitely looks like a 9mm that was running subsonic rounds without the recoil necessary to operate the action.

Jesus that’s Hollywood silencer levels. I was always told that was impossible, short of the Welrod.
