Well, let's see.
You take a Mossberg shotgun, which every fan touts because of the superior placement of the safety and action release.
Then you put a pistol grip stock on it, so the shooter can't reach either of those superior control locations without breaking the firing grip on the gun.
OoooooKay...
Fwiw, my 590/500s are all conventionally stocked. And yes, in fact I am an oldphart stuck-in-the-mud. But I don't have to grope my shotguns like a teeenager on a first date to get to the controls, either.
