Hello, first time here. I've collected all of the suppressor test data I could find for the Five Seven firing standard velocity rounds. If you know of other tests, I can add them here.

TESTED SUPPRESSORS & DIMENSIONS
These are suppressors in production with sound tests published. All have about a 1” diameter, except the Gemtech which is 1.25"

SOUND TESTS
* Differences in testing and/or ammo appear to make major differences in measured results. For example, the Sparrow is tested by two different sources below with different outcomes. The first five-shot average reductions are 30.88 db with SS197 (Silencerco video) vs 24.52 db with unspecified ammo (Silencershop videos).

Re: Suppressor tests for FN Five Seven
Yeah, 160+db, that's bonkers for a handgun. That's like 300mag loud. I bet with handloads using Longshot it's like 300db, that powder is stupid loud. The video comparo I came across between the Axiom and the Sparrow showed the Axiom quite a bit quieter, but different circumstances, altitude, etc so who knows. I'll have my Axiom around April, and I'll put it up against my Tirant9 with the old ear test and see how she does. Guess I should probably use 115s to keep it fair with the sonic crack.
