The recording levels from being outside will have a lot to do with it. There are videos of the difference between full power unsuppressed loads then suppressed loads side by side, the difference is quite apparent, though neither sound deafening on the video.[/QUOTE]
Great point, additionally, the position of the microphone behind the barrel vise in front of the barrel captures only a small percent of the down range sound. This might come as a surprise to some, but with the proper suppressor/ammunition combination, "Hollywood" quite is achievable - even down range.
Now here's another fun fact, One of quietest firearms I've ever used was actually a Smith & Wesson revolver. 4 inches of barrel and about 4 inches of silencer. And yes, it required some modifications at the point where the cylinder and barrel meet.
