I have a M19. I had to quit using .357 loads years ago due to wear issues (thousands of rounds). However, the action, both DA and SA, is just beyond description. Smooth, light and just a joy to shoot. I tried a number of Ruger DAs back in the late 70s. They just weren't as slick or smooth. That is actually a plus for LE as you are less likely to get and accidental discharge. I will say this about the Rugers, they are built like a vault. You can feel it when you handle them. I would imagine you would really have to work at shooting one loose if that were your goal. I'm thinking with 11 grains of 2400 under a 150 grain lead Keith bullet, you could never shoot that gun loose, ever.
