Ended up going for the BSS over the 870. What made me pick is the improved reliability/toughness. I know the internet is the internet but I kept stumbling on threads about the 870 express jamming/rusting and I don't feel like dealing with that. I really liked the simplicity of the BSS, less stuff to go wrong.
It ends up being a '77 with the sporter stock, 28" w/ BBLs. I like the vintage look a lot. Weight ends up being 6lbs 10.5oz. The stock is beat up but very usable and the overall condition of the gun is pretty good. I'll go test it soon.
Only thing that worries me is that it seems to have a full/mod choke, which from what I'm reading, is kind of tight for the intended use. I guess I should have done more research before but being a newbie I kinda trusted the store guys on that one. Not too sure which exact hunting situations I will encounter but is there a cheap way around this (small shot #, aiming higher) or I'll be just fine anyway and I'm overthinking it? The store sold me 2 3/4 1oz 7 1/2 shots and from what I gather, it might be burger time.
Thanks again.
