I wanted to add I bought a 659 ( round trigger guard ) a couple of weeks for 300 . It was in utterly terrible shape. Completely filthy. It still shot fine but upon cleaning it & taking it down I found a crack in the cheap black plastic back strap/insert that holds the spring for the hammer , after messing with it a little it soon completely broke. I've had a hard time finding the part. I've called smith twice , numeric was out of stock but Jacks first gun parts had them in stock. Maybe I'll post some pics .
