Oh, you have commented since I started.

When you say Greener action I hope you meant this one.

And not this one.

Even a standard MH action would be better. I have couple clean ones, that would work for your project.

That Greener shotgun action is pig and bitch to work on.Your gunsmith will hate you, if he really truely know how to work on a martini.

Stick with the Ruger 1 idea, even the Encore would better if the cartridge will fit
