SDS MAC 9 DS 9MM | 4.25″ Barrel | 17RD

The SDS/MAC 9 DS is a 9mm double-stack pistol built to a 1911-derived platform with a 4.25″ bull barrel and an optic-ready slide cut for RMR-pattern optics. It ships with two 17-round OEM Checkmate magazines and a removable competition-style aluminum magwell. This configuration suits competition and precision range work where capacity, sighting options, and a stout barrel profile support repeatable accuracy. A compact RMR-pattern red dot such as the Holosun 507K pairs well with the factory cut and remains comfortably under $1,000.
