It's a nice gun, but I'm not wild about aluminum/"Dural" frame guns. No, I don't have any evidence/experience that shows them to be inferior. I just prefer steel frames. The weight savings is meaningless. I have a steel frame 12x12/7x65R, and it's only a few ounces more than this gun.

Check in on Cabela's Gun Library, they usually have a few drillings. Also www.learmes.com. Champlin Arms, Bob Jones Guns, and www.pugsguns.com.
