I have mine butter smooth. I polished the hammer and bolt with Mothers. polished the inside of the body and pump guide.
I replaced the return spring with a ccm and clipped the stock hammer return spring in half and put that in too.
my gun cocks nice and easy and when you release the pump handle it returns on its own.
all the drag comes from kink between the hammer and bolt, which causes the hammer to rub on the body, so polishing the hammer is your best bet.
springs are longer then nelson springs.
cocker spring on the left, then 3 phantom springs and 4 nelson springs. hammer spring on the right.
