From the manufacturer
SIG SAUER ROMEO-X SIG-LOC(TM) PRO ENCLOSED REFLEX SIGHT The SIG-LOC(TM) (Leverage Optimized Connection) system was first concepted during the development of the ROMEO-M17, revolutionizing pistol-mounted optic integration with a low-profile, ultra-tough connection between the optic and pistol slide. Designed for precision and strength, SIG-LOC(TM) ushers in a new era of expectation and performance for civilians and professionals with the ROMEO-X SIG-LOC pistol-mounted red dot. SIG-LOC(TM) is an innovative mounting footprint that establishes five points of contact between the slide and optic to eliminate shift in zero created by extensive shock from recoil and harsh impa Mfg: Sig Sauer, Inc.
