I am the Instructor at our range known as "The Dinosaur".In the whole Revolver -VS- Semi Auto debate I am up front in saying when I carry 95% of the time is my Detective Special or Cobra riding with me. I will say with the exception of Security and Law Enforcement you need not worry about having 17 and 1 in the pipe.If you can't handle a defensive situation in 5 or 6 rounds and one tactical reload you need a SWAT team. Another point my instructor made that I found to be true is if you can shoot a DA Revolver well you can pick up any Semi Auto and shoot it well. Police may never go back to the sixgun but I am observing that a large percentage of new shooters are gravitating to the revolver. For the students who ask me about buying a decent revolver I tell them to get a older Model 10 or D.S. and stay away from the new ones.My Model 36 was a replacement for Model 640 Barrel launcher #2 and the barrel was twisting to the right.It took 3 trips to S+W before they replaced the defective barrel.the "Classic" Model 36 has a 720 dollar price. A decent D.S. can be had for less and you have the quality.
