Powderman, The silver screw on the handle. Get a wrench and completely take this out of the gun. You may have to unscrew the the adjustment screw as you loosen the hex nut. When you get it all apart, you will see a white plunger on the end of a small shaft that screws into the adjustment screw. Mine was loose and I had the same problem. Tighten that connection between the two parts up then reassemble. I would screw the adjustment screw into the hex nut before I put the hex nut in the handle. As you start to tighten the hex nut, pay attention to the adjustment screw and back the adjustment screw out if it starts to bind at all. If you do this until you get the hex nut tight. You should be golden. Greg
