Good evening
This is more than a simple barrel length swap. Take a standard DW revolver and make it into another caliber.
May be some thing so simple as a 375 Supermag to a 414 Supermag but still be able to go back to the original caliber.
Or a 44 Mag to a 45 Colt.
Or a 357 to a 32-20. This one may become a triple set as a 41 Colt just seems like something that I could enjoy as I already have a real Colt New Army 6 inch from 1907 in that grand ol' man stopper caliber.
So what have you done ?? I know there are a couple out there.
