The vast majority of my firearms experience is centered around high powered rifles. However, I am looking at adding a semi-auto handgun to my arsenal and I've always been a fan of Smith and Wesson. I love the fit, feel, and looks of the Sigma, but I don't personally know anyone who owns one, even among all of my gun nut buddies. I would like some reviews on the Sigma, pros and cons if you will. Any input is greatly appreciated.
