Stopped in the local shop today. On the shelf was a Model 66 no dash. Plenty of nicks and scratches, some crushed checkering on right grip panel. Shop owner claims it was a Chicago PD gun, and that "they were not allowed to shoot .357's, only .38's". Anyone know if that is true? The adjustable rear sight was black, not stainless (he had never heard of the stainless ones). To me, it appeared that the base of the black sight was slightly (VERY slightly) longer than the part of the frame it attached to (??). Could original SS sight been replaced? Little sign of flame cutting, forcing cone OK, lockup good. A proud old P&R warrior, but a little too used for what I'm looking for, besides, I want those SS sights! $475 on the tag...
