So, there's a Redhawk "convertible" now, that will shoot 45 Colt and 45 ACP (with moon clips). How is this done, I mean, what are the chamber and cylinder specs, and could this be done with other models? Consider the GP100 as a "baby Redhawk", and think of the possibility of doing this conversion so 9mm can be fired in it, too, with moon clips. What about a 454/45 Colt/45ACP Toklat? mind;blown.
