Holosun list the plate as taking their 509-series sights and the AEMS-MACRO.\u003c\/p\u003e\n\u003cp\u003eIf you are building on a Glock MOS host — an airsoft gas blowback slide, a training gun or a long-barrelled competition pistol overseas — this is the part that lets a sealed 509 sit low and square on the slide instead of on a stack of shims. Worth saying plainly: Holosun do not publish what fixings are supplied with the plate, so if your slide screws have gone missing, tell us what you have before ordering. The plate is also 9mm-specific and will not suit .40 and .45 MOS pockets.\u003c\/p\u003e\n\u003ch3\u003eWhy shooters choose the 509PLT-MOS9MM\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptic side\u003c\/strong\u003e — Holosun 509-series sights and the AEMS-MACRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHost side\u003c\/strong\u003e — Glock MOS optics-ready slides in 9mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFootprint note\u003c\/strong\u003e — the 509 uses a Holosun rear-lug pattern, not RMR and not RMSc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e — aluminium with a hard anodised finish\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuild\u003c\/strong\u003e — genuine Holosun part, cut to Holosun's own tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat the 509PLT-MOS9MM fits\u003c\/h3\u003e\n\u003cp\u003eIt fits Glock MOS 9mm optics-ready slides and carries a 509-series optic such as the \u003ca href=\"\/collections\/enclosed-red-dot-sights\"\u003eenclosed 509T\u003c\/a\u003e.
