Hoping you guys might be able to help. Was just getting ready to field strip and clean a brand new Shield(no safety model)and ran into a problem. It appears that a roll pin is in the way. I cannot fully rotate the takedown lever as it seems to be hitting said roll pin. The roll pin in question is the one furthest forward on the gun...the one that the takedown lever should cover when fully rotated. Can I just tap the pin in order to give the takedown lever some room to move? If I do this, should I do it with the slide locked back or closed? Or do I just need to contact S&W? Any help is greatly appreciated as this will be my son's 21st birthday present come June 21st. Thanks.
