The Glock 43X combines a compact-size grip length and a subcompact-slim slide for a variety of users. Three safeties disengage sequentially as the trigger is pulled and automatically re-engage when the trigger is released. Features polymer frame with an accessory rail and beavertail; advanced surface treatment of the slide results in optimal hardness by considerably reducing wear and tear and it makes it corrosion resistant; matte surface minimizes light reflection; the extractor serves as a loaded chamber indicator to comply with the laws of certain states and its position may visually and physically indicate whether there is a cartridge in the chamber of the pistol.MOS features a slide that is precision machined to provide a mounting system for popular optic sights. With multiple adapter plates (sold separately), you can quickly and easily mount miniature red dot sights.*Note: The G43X with the Modular Optic System (MOS) does not come with adapter plates. Includes 2 magazines, mag loader, cleaning set, pistol case and gun lock.
