One other thing to consider about American suppressors is the innovation, technology, and materials they're being built with now. I've only got one suppressor for now, a .30 Caliber/7.62mm rifle can called the Vox S. It's made from a nickel maraging steel alloy that's typically used in aerospace and rocket parts and other high temperature applications where repeated cycles of heating and cooling happens. Then you have the newer flow-through cans to greatly reduce gas backpressure where the whole thing is essentially 3D printed, but with metal, because the design is far too complex to be machined. You also have suppressors now where each section of the baffle stack and the body is one piece and can be threaded on to the section before it, so you can customize the length and quietness of your can. You have cans utilizing other more exotic materials like inconel and Haynes 282, which are much more expensive than steel, aluminum, and even titanium of older suppressor designs. Since sound suppressors have been treated less as a utilitarian safety device in the US and more like military equipment or a niche collectable due to the National Firearms Act of 1934 up until recently, our suppressor manufacturers have had to innovate to stand out from the crowd and attract buyers. But now that suppressors are becoming more mainstream and accessible to regular folks, hopefully they will get deregulated and be treated more like they are in Europe.
