Hello, As a favor to my father-in-law I've been restoring his 1949 Stevens 5100 double barrel side-by-side. I disassembled it and sent the metal off to be re-blued and ordered new stocks from Boyd’s. I did not disassemble the receiver portion. I’ve got it all back together yesterday but in testing it unloaded I can’t seem to figure out how the triggers/hammers get cocked after firing. If I remove the stock I can access the hammers and pull those back and it resets the trigger. But if I dry-fire it, break open the barrels to simulate a reload, and close the barrels again, the triggers don’t reset. I’ve never worked on a shotgun before, only using my 870 for light hunting. Any advice on how this is supposed to work would be appreciated. Thanks!
