The third generation Smith auto's are actually well made, and reliable weapons. Police sales faltered with the introduction of the plastic frame pistols, like the Glocks, as weight on the belt matters, and the striker fire trigger is easier for new shooters to learn then a long D/A, or D/A to S/A pull. . Other departments with money to spend want the exotic, like the SIGS. My agency used them for a number of years, and they always worked well. 19 years as a LEO firearms instructor, and I can tell you most semi-auto malfunctions can be traced back to bad ammo (usually reloads), and damaged magazines, usually damaged when ejected from the gun onto the ground during combat drills, often being stepped on in the proccess. I have seen my share of revolvers fail, usually a binding cylinder do to lack of lube, or primers flowing into the firing pin hole, gunk under the ejector star, or backing out against the recoil shield.
