Mine has been flawless. Berry smooth action and very accurate. My wife has claimed it for her. Oh well I'll carry my 617.
I have a S&W 65 3 inch barrel which weighs more than the 605 and I too found the 125 grain a bit too much. I went down to the 110 grain for the .357 much more pleasant to shoot. Ballistics (muzzle energy) similar to a 9MM.No issues with mine--rubber gripped shiny stainless 605, made in 99.
Wow- did put some of the Federal 125 gn rounds through recently--not pleasant!
