Since 9mm ARs are blowback operated, would a suppressed AR pistol be significantly quieter in 300blk (both shooting subs) since it is gas operated? Anyone have both and can comment?

Sorry, I was referring to suppressed subsonic. Fixed the OP.I have both in SBR form.
Are we talking about subsonic or supersonic loadings?
Yeah I was thinking I was getting some ejection port noise from my 9mm and wondered if the gas system would be quieter, but the guy with both says no. I'm running the Slash 9Q heavy buffer so I don't think I could delay the blowback any more.My short 9MM SBR is 4" barrel and has a lot of port noise that my 10.5" 300 BLKout does not have. 9MM is cheaper to shoot and lighter overall with a lighter can. Both are fine without ears but I'd hunt with the 300 and shoot steel with the 9MM.
You ought to be able to find somebody with a 300BLK that will meet you somewhere compare. Sounds like you have a 9mm AR, right?Since 9mm ARs are blowback operated, would a suppressed AR pistol be significantly quieter in 300blk (both shooting subs) since it is gas operated?
