Primer slide assy

Have loaded about 6-7 thousand rounds 9mm and this problem has slowly appeared. When the primer cup comes up to seat the primer it is ever so slightly off center and rubs against the plate. Then it has a slight catch and causes the primer to jump off center or even flip upside down. How do I adjust and center that area. Part # 13621 and 13967.

RE: Primer slide assy

The most likely cause is that the set screw that secures the primer punch and cup in place has loosened, and the cup & punch are too high. Remove the primer feed from the frame, then detach the primer slide. Using in calipers, measure from the underside of the slide bar to the top of the primer cup. It should be 1.410", +/- .003". If it is, use a clamp or vise to hold the punch and cup down as far as they will go, then tighten the set screw.
