I’m pretty sure everyone here knows how the Special Forces guys wore out M19s by shooting lots and lots of 125 grain jacketed hollow point ammo, experiencing flame cutting of the top strap and loosening of the gun. The standard yarn has it that S&W solved the Model 19 “problem” by developing the 586 and 686. What I would like to know is if any other strengthening efforts went into the Model 19, similar to those done with the Model 29, especially the -4 and -5 iterations. I’m not really lusting after a heavier .357, as I won’t be running thousands of hot loaded 125 grain bullets through it, but I would enjoy a Model 19 4” or 6”which would not develop premature end shake or quickly lose the ability to tightly and precisely lock up for the shot (timing problems). The most recently made Model 19 I have owned was a 19-3, so my knowledge about the dashes since then is very limited. Thanks for your answers in advance!
All the best, Dave
