The dovetails are the same size, as Sig uses the same sights for 90% of their firearms, the only difference in some cases is the height. For a dovetail mounted aftermarket sight such as the Burris, the curvature of the top of the slide may be a little different. Looking at both my P220, and 2 P226 models, I can not notice any major differences. The .40 S&W P226 uses the same sight set as the P220, and .40 S&W P229 if that helps!
