Standard Novak sights will not fit your s&w Pro Series 1911. Unfortunately, s&w uses a proprietary Novak style cut in its 1911 pistols. I have done a lot of research looking for aftermarket sights for s&w's 1911 e-series. Hiviz, Trijicon, and meprolight, all make sights for s&w 1911 series guns; however, they do make a distinction for Performance Center 1911s, as PC guns have a different size cut. I am fairly certain that Trijicon makes PC sights for s&w. I would contact each of these manufacturers to verify compatibility.
