Just bought a new disconnector from Poland since my old one had worn to the point where it would not decock the hammer with the safety on. New one decocks the hammer fine but now the gun will only slightly move the hammer and release when pulling the trigger double action. The top of the new disconnector looks a little different than the old one. Do I need to modify it in order to make it work?

Yes probably. The disconnectors come a little large brand new and may require fitting. Search this forum for "disconnector" and you should find threads talking about it. Be weary of taking to much material off as you'll put yourself back where you started.
