Hi I have been looking for information on my Stevens db. I got it this past spring and when I shot it, I would have to unset the safety as it would set after every fire. I took it in to have the safety spring replaced, and the first time I fired it after getting it back, it fired BOTH barrels! Now when I crack it open to load/unload, then close it again, I can pull either trigger and it will fire. I was under the impression that when I opened it, it would set the safety automatically. Am I wrong on this? Please help!
