The funny thing is the utility of sites like Pew go down as you buy more suppressors lol.
I’m guessing more experienced suppressor owners start caring less and less about dB or dB-like numbers. You’re more interested in the stability of the suppressor company, the suppressor’s construction, length, weight, etc etc.
For example, I’m looking for a dedicated suppressor for an AR15 and caught myself comparing dB numbers and the thought, “Wtf most modern suppressors will quiet the shot down enough. What I really don’t want is the gas to the face.”
Seems like a main audience of Pew’s is n00bs. Another audience is nerds. TBAC’s open suppressor standard and testing might eat into that n00b segment quite a bit.
