I've recently inherited my father's old Franchi semi-automatic shotgun, I welcome any suggestions you have for servicing this firearm. This is the shotgun that I fondly remember my father using while he taught me about hunting, and firearm safety and maintenance. I know that he bought it used in the 1970's, (I hunted with a cheap shotgun that I bought from Oertles, with money from my first job as a dishwasher). I thank you in advance for your suggestions. Have a great evening!
