oh yeah c**p thats the trigger pin thing, i will have a look for it and try post it to you. I just took all the bits off my ion and sent them to you. the reason i didnt send that screw was it wouldnt tighten up on my grip frame, just seemed really loose, so i used the one i sent you (not sure where it acme from) i will have a dig around and and try find it but it basically made the trigger to loose (side to side movement)
PM me say sunday so i remember as im quite busy this weekend. but just so you no it will work fine if not better with that pin
