I had three of them back in the mid 80s; a 4 inch 686, a 6 inch 586, and a 4 inch 586. Excellent guns! I have since gotten away from a steady diet of full magnum loads and find that a 4 inch Model 19 suits me just fine.
If I were a uniformed police officer, and allowed to carry a .357 revolver, a 7-shot 686 with a 4 inch barrel would be the one.
