The Lictor G9 magazine carrier is designed to accept mil-spec magazines from all of the Big 3 modern service pistols (Glock 17/19/45″ Sig M17/M18″ and Beretta M9), and also happens to fit a variety of other popular commercial-market 9mm/.40 caliber pistols with similar magazine dimensions (such as the CZ P07″ CZ-75″ Beretta APX, Beretta PX4″ Walther PPQ, and Springfield XD and XDM).
