Model 64s are special. One can never have enough. The old service-style grips with a t-grip adapter fit most people. They fit this people swell! Many on the used market are police or security turn-ins. They may be scratched and dinged on the outside, but have been fired very little, have good bores and smooth actions. If you have one, it is a keeper. As Ayoob said, it is small enough to conceal but big enough to look menacing.
