Yes, a Model 64 is the stainless version of the Model 10. As such, it is a great "general purpose" revolver. Model 10s and Model 64s were very popular Police revolvers. Model 64s came in both round and square butt frames and barrel lengths of 2, 3, and 4 inches. The first few years of the Model 64 had the standard or "pencil" barrel, but this changed to a heavy barrel which is now the standard. They don't have the extras such as target hammers, target sights or target triggers, but they are an accurate and dependable revolver that is suitable for a variety of uses. I have a few Model 10s and a 64 and really enjoy them.
Hope this helps.
