need advice please. My wife bought a SR9 and we are having issues stripping the slide. The back plate on the slide is supposed to have two holes. the larger hole centered on that slide you see the rear of the striker pin assy. The other hole in a video that we watched is a small hole used for removal of the plate for further strip of the striker pin. We seem to have a back plate with only one large hole and none for plate removal. Is there another method other than shown for removal of that plate?
