I have a very old Mossberg 500 (approx 50 years) and I took it down the other day to clean it. I put it back together and the hammer engaged, did it twice, so I was satisfied that it was working. The next day it wouldn’t shoot, so I took it back down, removed the trigger assembly, and the trigger wouldn’t release the hammer. I’m not sure how to troubleshoot the issue any recommendations would be great.
YouTube is your friend, I don’t know anything about them but there are a few full disassembly videos
Hope it helps😔
Yes sir I definitely agree 100 percent with @Adamant. Any time I have an issue with any type of firearm I search it on YouTube channel.
