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. Includes three magazines, mag loader, cleaning kit, pistol case and gun lock. *Note: The G43X with the Modular Optic System (MOS) does not come with adapter plates.
