SIG Sauer M18X
Best optics-ready sidearm for shooters seeking professional-grade performance and control.
This is the ultimate evolution of a proven military service pistol, now refined for the civilian shooter who demands out-of-the-box readiness. By integrating a ruggedized red dot and enhanced grip ergonomics, it trades the simplicity of a standard duty sidearm for superior precision and faster, more intuitive handling.
