For the IWI Masada Slim/9S – Our Masada 19587 Tru-Dots *rear* sights will hang over the back of the slide so they will not work. The 19587 front sight, on the other hand, is the exact same dimensions as the OEM front so you could replace just the front if you wanted to. The MPN for just the front is 0195873107.
Otherwise, to replace as a set, you would have to go with a Sig set (10110 for Tru Dot) or our 49587 Hyperbright Masada’s (which are repackaged #8/#8 Sigs). The OEM white dot sights that come on the Masada Slim/9S are non-tritium, but still Sig dovetail dimensions. The Sigs are significantly shorter than the OEM height of the Masada sights so you wouldn't be able to use a Sig rear with a Masada front or vice versa without severe POA/POI issues.
The Meprolight IWI Masada Fixed Self-Illuminated Pistol Sights Set are not suppressor height. They are the same height as your OEM set.
