(5 out of 5) Great gun but expensive.
by Theodore from Chicago, IL on January 9, 2018

Great gun heavyish trigger great front big dot night sight. Lighter than Airweight J Frames. Spend half the money and buy the 442. I own both. Used Sportsman's for my M&P 357. Great service and price. BTW, if you're deciding between this and the 340PD model, buy this one.
