Thanks for the link Dano. Unfortunately, they did not have the barrel I am looking for.

I just bought a pre 1977 1100 in 20gauge. I’m having a very difficult time finding a slug barrel for the gun since they were manufactured on the 12 gauge frame at the time. So I don’t have the option of buying a new one. Has anyone seen one around or have any suggestions that may help me out?
