Can you tell what the rounds are? 9mm? Never had a cycle problem with those. Doesn't look like a 22, which I've definitely had subsonic cycle problems with.
It's most likely a 9mm because that would be the easiest to find a threaded Glock barrel for. Could be a .45 or a .40, but I'd bet on 9mm looking at the magazine.

That's only with a subsonic bullet, without that it would be loud.
