I have a friend that made a PPC gun in 44 magnum, looks like a truck axel foe a barrel. But boy howdy does it shoot. Local gun show had a PPC gun made on a Colt Trooper III with heavy bbl and aristocrat sight rib. Asking price was $700. Wonder what he was smoking. Think Clark Custom Guns does some PPC guns on the model 10. So maybe pick up a gently used model 10 and have at it as it already comes in 38 special. Frank
