I recently purchased a M629-6 Mountain Gun in 44 Magnum. The revolver had a very large and unsightly gap where the barrel shroud meets the front of the frame. I contacted Smith, and they paid shipping to return the revolver for inspection. They replaced the barrel and front sight, and adjusted the crane. But, the the gap is still there. It will easily accept a .007 feeler gauge with the cylinder opened. None of my other Smith's have this gap, to include a 617 bought a month before the 629. Smith told me the gap must meet their specification or they wouldn't have returned the revolver, but has finally agreed to accept it for service again after a few weeks wrangling. Does anyone else have th esame problem with a recently purchased Smith? Tony
