Without the use of high speed photography it would be hard to know for sure, but when I talked to Jeff he made it sound like he didn't think that the pistons actually open until the operating sleeve slams into the receiver and the piston can't travel any further. I don't know when the piston actually opens and I won't pretend to, but I do know that neither of my guns showed any accelerated wear after running the sealed pistons. My Maxus did not like the stainless sure cycle system though as one sping was to heavy and caused jams, the other one being a bit too lite and did show a bit of receiver hammering.
I have found that with a 28" barrel on my 3.5" Silver, the piston might be opening, but it doesn't affect how the gun operates unless a heavier than stock recoil spring is installed. And even then, it doesn't make much difference changing from a Mag (lightest spring tension) piston to a sealed piston. It'll cycle everything with a 28" barrel, and spit 3.5" empties over 15 feet away.
However, with a 24" barrel, the gun won't cycle 2-3/4" or even 3" mag loads with a heavy recoil spring installed.
No matter what piston is installed.
With a sealed or Sporting Clay (SC) piston installed and a heavy recoil spring installed, it will only cycle 3.5" loads.
With a factory 3.5" recoil spring installed, it will cycle the lightest trap loads I can find, with a sealed or SC piston, but not with a Mag piston.
With a 24" barrel, Mag piston, and factory recoil spring, it's a 3" and up only gun.
