I have a 3 inch police trade in Model 65. It was dirty but cleaned up very nicely and is a tight carried much shot little revolver.

The 65 has fixed rear sight and when I installed a bobbed hammer (factory hammer) it became a wonderful cary gun. These are $300 to around $425 guns but your selection varies from time and place. I was happy to find a dirty one for a cheap price, that had great lock up.
