I carried a Model 19 and dearly loved it for what it was: a light, powerful, accurate and smooth operating duty gun. Advance 30 years. I had found both a nice Model 19 at a gunshow, and an equally nice Ruger Security Six at gunbroker. Side by side, as stated, the S&W was smoother, but I had recently had to trash a Model 10 S&W barrel, because the forcing cone had split. The S&W 19 has also had a history of similar failures with too many magnums being fired. I wanted a .357 that would last and be my ONE .357 for general use. The Ruger shot like a laser beam, and the fact that it will stand up to more .357's than the Model 19 made it my choice. I sold the S&W, in spite of my nostalgic attachment to the model from my experience with it long ago. The Ruger will serve you longer, and can always be tuned for a great action job.
