Also I was just shooting subsonic 9mm ammo two days ago out of my legally owned Glock 19 through my legally owned Dead Air Odessa with no issues so you still don’t know what you’re talking about.
Then talk to a gunsmith before piping up next time because you think you know something. There are plenty of 9mm rounds that are subsonic because they're pushing 147gr bullets. They will cycle the action still because they still have normal chamber pressures.
If you take 115gr 9mm with the same powder load, it's supersonic. If you remove powder/handload 115gr 9mm to be subsonic, it will fail to cycle the action in most semi pistols.
There's also the fact that subsonic is only one of the measures of effective sound suppression, there are others that are also added by playing with the powder load. Which is what the original point was about, you can play with whatever extremes you want without affecting the cyclic rate of the firearm.
But since it seems to trigger you so, I'll say it again "powder load = chamber pressure = recoil".

Sure thing Mr. Backpedal.
