I threw away the primer feeder system from mine. Too many jams and problems which eventually ended up with me ruining a new HK USP 45 tactical.
Now I run all brass through it with only the sizer/decapper, then inspect every piece for primer size and any problems with the brass before priming it with my RCBS hand primer, then I throw it all back in the hopper and put the expander/powder die in and the seater die (I leave the sizer in but remove the decapping pin so the brass stays lined up in the tray). It takes longer but is much safer and more consistent.
You will probably need a new brass feeder system (as mentioned earlier) for large pistol, I have complete case tray, die holder and feeder tubes for 9mm, 45auto and 10mm. Wholesale sports carries all of it most of the time.
Good luck and be careful.
