I bought the .45 Colt Mountain Gun and am happy I did.
First of all, I hate moon clips. Second, you can shoot anywhere from Magnum Cor Bon's to low recoil cowboy loads and anywhere in between. Third, I really like the gun itself! Fourth, the .45 Colt is all about revolvers and has a history to go with them. Fifth, I love being able to use the same load in my handgun as I do in my lever gun! Sixth, you can use the Mountain Gun as a carry gun, a nightstand gun, a bear defense gun, a dear or wild bore hunting gun and a plinking/target gun.
As for the gun itself, mine is a fine specimen! It sounds like some may be lacking in the finish department? But, just look at the gun, if it has a finish that isn't up to par, get a different one. I would swear the gun comes with an action job from the factory, I don't know if it does but, the trigger on mine was great right out of the box and has only become better. The sights are great as are the Ahrends cocobolo grips! The Mountain Gun is very well balanced gun, it feels good when you point it and does so naturally.
I know a lot of people like the .45ACP, as do I but, IMO they're better for semi-auto's, that's what they were designed for after all.
