I have a XDS in 45acp and I'm wanting to put night sights on it, I've heard that the standard XD night sights will work, is this true? If not do they make NS that are fit for an XDS if so what do they run.
I don't think they will work. A while ago I spoke with Springfield and they have several options. One option is Trijicon, they have systems that are specific for the XDs. https://www.trijicon.com/na_en/products/product3.php?pid=SP102-C-600752 That's a link to their HD night sights for the XDs.
