I have a four inch 27-7 #75, that I purchased for a duty weapon when they first came out. I tried to order #50 to match my badge number but alas, it was not available. I carried this revolver until I retired in 2013. It led a rough life, I had to replace the rear sight assembly after I fell off a cliff one night during a rainstorm. And again after a antelope kicked it while I was removing said antelope from a fence.
