Completing the line between main production and the Performance Center, Smith & Wesson's Pro Series represents the next step from standard models. These firearms are offered with a variety of enhancements yet still remain true to "stock." Bringing competition specifications and features to factory models, the Pro Series offer that ready-to-go package while still maintaining production line integrity. This Performance Center Pro Series features an oversized external extractor, a three-hole curved trigger with overtravel stop, full length guide rod, and a grip/ambidextrous thumb safety. It also has a stainless steel barrel and slide, Scandium alloy frame with an overall black finish.
