1187P essential parts

[corbon]

What parts are necessary spare parts for a Remmy 11-87P? I searched this and there were a lot of different answers. What are high failure parts do I absolutely need to have on hand if I was planning to attend a shotgun class (all jokes aside, besides another shotgun), i.e. springs, barrel seals, etc? Thanks.

If you have maintained it, you should be able to go about 300 rounds or so without any work. If you are going to pass that mark, then I would certainly have a spare o-ring with me. The "failure parts" are more "wear" parts and changing out one or two may result in other function issues.

With that said, I'd have a carrier, carrier latch and the pins, or preferably, the whole carrier asembly. Also an o-ring, a piston seal assembly, and an action spring. I pretty much rebuild mine with these parts every few thousand rounds.
