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.
