Hey again guys, when I first joined last year it was to try and get help with my old Stevens shotgun. Well I decided to stay around, and now i'm back with more questions! So last time I talked about this, I was popping primers in one of the barrels (the stevens 335 is a SxS 16 gauge.) I took the thing apart and filed down the firing pin in a attempt to smooth it out and stop popping it. After I finally got it back together, I took it to the range. It still pierced the primers, but it also started to occasionally fire both chambers at once. I cannot replicate the issue by dry firing on snap caps. Safety still works properly as well. Also, once in a while it gives me difficulty with opening it up to eject the shells. The firing pins are stuck out and don't seem to be resetting completely the first try. Does anyone have any suggestions on what it could be? It is honestly such a pain in the @$$ to put back together that I haven't bothered with it for months. I'm considering just buying all new internals in a year or so, but that would cost me around $150. Would I be crazy to put $150 into a 100 year old shotgun? Any and all advice is more than welcome, thanks guys!
