I recall when my agency replaced our aging Model 15 w/the new stainless revolvers, 4" for uniformed and 2" K frame for commanders & detectives. Many had to be worked on at the range and several went back to the factory so it seems little has changed from the late '70s. I don't mean to knock S&W, they still produce one of the best revolvers on the market. It could be that market forces have impacted all firearm companies b/c it seems they all have similar problems.
