Can anyone recommend a shotgun gunsmith who can tighten up the action on a shotgun that I gave my son. It belonged to my father who acquired it in the 1950's. It is probably a liberated WW II 16 gauge SXS that is well made and appears to be Spanish. My son loves that shotgun because it fits him very well and he has killed lots of pheasants with it. The action is getting loose and the problem appears to be that the hinge pin is worn. Thanks for help, Fred
