Great revolver, look at the bottom of the forcing cone(end of the bbl inside the frame)and the frame underneath the bbl. Their only real weakness was in this area, as they would crack if they fired a goodly number of 125 357s.
The gun is tough if it is kept clean and fires 158grain 357s or any 38 Spls. It was engineered before the 125 firebreathin 357s that became popular in the 1970s and 1980s.
I've had one for forty years and it is still perkin along. Very accurate, easy to carry and powerful for most any Self Defense need. They also make great plinkers with 38s.
