Whatsoever aspect just isn't working…try everything with stock OEM components. Occasionally aftermarket slides and triggers have too limited tolerances to work in a P80. To this point the Brownells and Grey Ghost (a bit limited) have worked in my builds. I’ve read ZEV slides may very well be also limited. https://socialaffluent.com/story4100741/a-review-of-glock-43-p80
