I couldn't resist buying a 4" blued version in as new condition. Are these strong revolvers and able to handle the heaviest loads? I have a Colt Python but this one feels so light and easy to handle that I wonder if it has the same rugged durability as the GP100. It showed up in my local gunshop today and for $299.00 I thought it was unlikely to find one this clean for less so I jumped on it. I almost bought a similiar Speed Six for $350.00 a couple years ago but I gotta have adjustable sights to be completely happy. It has a warning on the barrel so I assume it is one of the last variations of this revolver.
