So I went ahead and bought one, cuz it's as cheap as converting a perfectly good shotgun. It swaps barrels with my dads Winchester 1300 but the magazine tubes are different sizes and lengths, so while the barrels match up, they are not interchangeable.
I recon it will shoot like the 1300, that've been if ere I see the sweet sunshine upon my face long enough to do such a thing.
I also bought a cheap laser sight that rail mounts at the gun show for $25. While it currently sits before the trigger on my 9, it will eventually come to rest upon the side of the savage, providing she proves trusty. I think attachments will be like any healthy addiction, always one more thing.
While we're on the subject, ghost rings or just keep the bead?
