Just wondering why I never hear my plenum filling with air after every shot? I never get that "hiss" sound like I hear on video's with fx airguns. Rifles always shot great and very accurate. Is this normal?
No Hiss sound from plenum 🤔

It depends on the caliber/power level you have your FX at!.....shooting 34 gr slugs@80+ fpe...
I always hear the plenum filling...
But if I dial it down for pellets, I barely hear it sometimes..

Yep, just means you’re sipping air instead of taking big gulps. My M3 compact .22 is silent. My .25 isn’t shooting heavier slugs.

I'm using a 30 maverick with 44g pellets on power6 for 870-75fps. On Pw7 it shoots 44g at 915 fps still no sound

Do watch your 2nd reg pressure Gauge...
If it drops when you shoot, the rise to the set pressure....Then everything is OK...
Also you say your M3 is shooting great...So there is nothing to worry about!
You may have a Quiet M3

I can hear the plenum on my Mavericks. I cannot hear it on the Impact. If I shoot too fast with the Maverick I get velocity variations because it needs to refill the plenum. Never have that issue with the M3.
It may be the pressure differential between 1st & 2nd regs. My Maverick is about 30# and the M3 is 50#. I have been told that is the difference and have been told it has nothing to do with it.
