Hello all. I'm brand new to this forum and have found a ton of great information here. I recently acquired a Model 657 4" and a no-dash Model 66 from the daughter of a a late LEO friend of mine. The 657 was shot less than a couple of hundred rounds as he had just got it in 1986 when an arrestee pulled out a gun and started a gunfight. My friend (standing in a crossfire situation) took a round from his partner's .41 that passed through the guy who had shot at him. My friend's injuries ultimately ended his LEO career and he passed away in 2001. Since that time, his guns were left to neglect and rust. The 66 is still slick as glass but the .41 needed some attention. I cleaned the action and noticed that he had clipped about 1 1/2 coils from the rebound spring (he was a S&W Armorer) I have the gun running great now but plan to replace the rebound spring with a median weight spring in the neighborhood of 15 or 16 lbs. The outlaw didn't survive rounds from the .41 that summer night in 1986 and the gun has never been fired since that time. I plan to change that soon and am quite honored to now own it. My first duty revolver 40 years ago was a Model 57. I'm always interested in learning from other Smith and Wesson Revolver owners and operators.
