The MAT-9K Full Pistol from Matador Arms is a roller-delayed 9mm platform designed for reliability, modularity, and modern control features. The pistol utilizes ambidextrous upper and lower receivers along with a 1913 Picatinny rail for mounting optics and accessories. Compatibility with Glock magazines provides broad magazine availability, while the Last Round Bolt Hold Open system enhances operational efficiency. The roller-delayed system developed for the MAT-9K upper helps reduce recoil while allowing for a lighter overall design and consistent cycling. A bufferless operating system supports compatibility with folding stock or brace setups, increasing portability and adaptability. The platform also features a non-reciprocating, reversible charging handle, allowing configuration for right- or left-handed shooters in a compact, American-made pistol platform backed by a lifetime warranty.
