From what I've heard, Clague and TKO are very busy making LDCs that may not be as good as what you have designed.
I have one device on my P-rod that replaces the stock Marauder shroud spacer on the muzzle with a flow-through spacer and a reverse-cone air stripper out in front of the muzzle tip. That one has potential to work really well because the air can get back to the large shroud area.
From my trial-and-error experiments, it seems once you have enough volume to capture the shot volume, that is as good as it is going to get for the air noise and adding more does not make it any quieter. If you boost power in that same gun, you may exceed the quieting capabilities currently on it then adding more will help.
The other noise like hammer hitting valve or the hammer spring twang becomes the loudest noise (assuming the ping has been eliminated).
