My grip occasionally keeps the slide stop from activating on empty. All my Walthers get a slide stop chop to negate the issue. Doesn't look like much, but a big difference for me on the range.
Remove slide stop, cut with dremel cutting wheel just behind where the slide stop actually engages the slide (definitely don't want to change that dimension by mistake), file a rounded edge and clean up burrs, dremel with very fine grit sanding drum just to remove file tool marks, dremel polishing wheel with polishing compound, Birchwood Casey Super Blue to finish it, reinstall slide stop.
Takes me about 20min. Luckily the slide stops come out easier on these steel frame versions since the frame doesn't flex when you whack it with a punch.
