When my grandfather passed away a couple years ago he left many things to his family. One of the many items was a Remington 870 12g pump made in 1965. He left it to my father who does not like guns at all. I asked if I could have it and my father was happy just to get it out of the house. Its has 150 year anniversary stamped on one of the sides with a Skeet rail site (I know very little about shotguns so please bare with my terms). I took it to the local gun shop and all they told me was that it was "a good gun". I'm looking for a little more info. I don't have a Sr. number but I can post it tonight when I get home if needed. Its looks to be in very good condition. The bluing still looks fresh. The wood still has a bright shine and the action is very smooth. I took the gun apart and was not able to find one bit of rust. My father says there where only a couple hundred shells at most fired in its life time. It has a long barrel, not sure of the exact size. From what I can tell it will only hold 3 shells+1. Is there any way to extend that tube to hold more. Also can a tactical stock and much shorter barrel be put on? I would like to be able to have this gun next to my bed at night for defense. The wood is in such great shape I want to take it off and store it so that it does not get banged up. Thanks for the help.
