I do not have own, but I did own a 908 for awhile. The good was S&W reliability, accuracy, ergonomics and price. The bad was (for me) plastic guide rod and plastic sights. Both of which I remedied right away. I also had to buy a holster specially for the 908, because like the 457, the slide is too square for it's non-value 3rd Gen counterpart's holsters. Bottom line; it's almost everything you would love about a 4513 for (in most cases) a lot less money. An actual owner of a 457 or 457S should chime in here shortly.
