Over its course of production, there have been some SD9/40VE models produced where sights may have been fit to the slide. Since our introduction of the M&P pistol sights, we have seen adequate evidence to support the majority of the dovetails on these models are different enough from the M&P dovetails to not recommend these sight for use on the SD9VE and SD40VE models. At this time, we do not offer sights for these SD9/40VE pistols.
