This is one of those things where the theoretical meets reality.
Out running a Benelli trigger isn't particularly difficult. But other than doing mag dumps into the same spot just to see how fast you can do it, it serves no purpose. (Then you start to play the game of "go as fast as I can without going so fast it doesn't work. You work on your timing and rhythm. Sure it can be silly expensive fun a for a few minutes, next thing you know you wasted 125 rounds and didn't really learn anything. lol)
"Damn, I can't do something that never actually happens!"
So it's a "problem" that's not really a problem.
As to the WHY, it could be that the Panzer is over gassed (and beating itself to death). So the fact that it can do something you don't need to do might not be a good thing.
