well, most likely the barrels walls are too thin anyway...an then there is the possibility that installing screwy tubes may change the regulation of one or both barrels...which causes some buyers to hesitate or pass...

opening chokes is a far more practical idea...i would think...

and of course, there is the fact that different ammo brands and different loads sometimes provide different patterns in the same gun...
