Hey guys. I recently did some mods (hammer strut, firing pin safety, etc.) to my GSG-522 and am now working with the trigger. I am in the process of welding that plate for the trigger pull and was wondering if the trigger is suppose to have slack going forward? It shouldnt move forward at all right? Just the pull and the return from the spring right? Hopefully you guys can help me out. Thanks Jon
