Simple question here. Why do people use the X valve on pump mags? To me the shear idea of it is like putting a Ferrari engine in a minivan, just to go get groceries. You not only are loosing the one advantage of the X valve(the reactiveness/recharge of the valve) but you are also removing the L10 bolt for a L7 and controlled bolt stick.
I only ask cause i am gathering parts for my own pumpmag.
