I am having problems lifting the slide from the frame, following the directions. Remove magazine, push barrel lever forward, swing barrel completely forward, cock hammer (safety off), retract slide 1/8". But the front end of the slide will not lift far enough to clear the frame's barrel hinge, preventing the barrel moving forward and off the frame. I have applied a fair amount of force without trying to hamfist it and break something (I'm actually somewhat well known for that around these parts). Any suggestions? Thanks to all.
