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).
