Every review I've seen on it is overwhelmingly positive. They attribute tighter tolerances due to advances in modern machining and fabrication to guns that are very close to the handed fitted originals. They've also addressed some of the known issues the original had, particularly with timing. While the action on the Python was always better than the S&W, the Smith always had better timing and lockup...so I've read. That was the reason for the "Smolt" competition revolver - a Python barrel mated to a Smith and Wesson action.I'm not sure that this re-release gets good reviews.
