I am currently under construction of a single snap barrel shotgun when I came across something which is holding me back from finishing the design. the trigger system, so I am asking what would be a simple design for a hammer shotgun.
If progression goes as planned I will post an end result in the next 2-4 weeks and will later begin designing a three barreled shot gun if possible (one .308 over two 12 gauge)
I have access to almost anything that I'd need for this project.
