So when I changed duty stations I had to disassemble my shotgun so the movers could ship it. When it arrived here there was a piece missing and in the course of trying to get a replacement I realized I don't know what the piece is called. From looking at a schematic I think it's the hammer pin, but I am really not sure and I don't want to order the wrong part. Looking at the below picture could anyone tell me which pin I need to get? It's a Remington 870 Express Magnum 20 Ga. Thanks.
