I used a hammer and brass punch, but I was very very carefull. A press or making your vise into a press would make things go MUCH easier.[b said:Quote[/b] (E.T. @ June 09 2003,8:36)]3. it's recommended not to use a hammer to drift out the roll pins but to use a hydraulic press instead (I know, I'm lucky enough to have one from where I work). I completely wrapped the gun with thin cardboard layers and tape in order not to scratch the frame during the (dis-)assembly.
