I have a 2.5" Model 19-3 that Mag-Na-Port went through when it was new - porting, action job, etc. It has absolutely the best action of any S&W I have ever handled, the single action is light and crisp, and the double action is unbelievably sweet - so smooth it is unbelievable! They always did, and still do, superb work, and your guns are fine examples. Enjoy!
