Sir, no offense but you do have problem with understanding what I have wrote. I urge you to read it again, slowly and carefully.
The trigger shoe replacement was done by Mr. Holm. I do use his service for my VP9 all the trigger jobs. You asked what I have done but not who done it. Then I specified that I did bunch of stuffs on my "Original Slide". You know, one that has been on the frame when I first bought it. Not the new long slide.
Again, the trigger pull bottoming out occurred from the beginning when I first tried out from fresh out of box. And guess what? It got fixed after HK replaced the firing pin. Only the firing pin, nothing else. Get it???
Now, has this cleared everything for you? Some ppl see and read only what they want to read and see. Hope you are not one of those.
