Engineering and Performance
The Firearm Suppressor industry is still in its infancy, and it will probably remain that way until the archaic taxation penalty and bureaucratic log jam are removed from these devices.
The potential for preserving hearing health is great enough though, that people are optimistic that the law will be changed to allow the free market to lower the cost of these items.
Here is a little “inside baseball” look at the engineering behind baffle pattern design in a Soteria suppressor. This video actually shows what goes on inside of a suppressor when a shot is fired.
It's baffling (no pun intended) to consider the variables that go into producing a "perfect" suppressor for each and every firearm/ammo combination.
