The Sig Sauer 8901566 lets you utilize a slide-mounted reflex sight without the necessity for suppressor height iron sights. With its factory-installed ROMEO-X PRO optic, the sight sits extremely low to the slide, enabling the use of standard height iron sights when the optic is not operational. This provides a consistent and familiar sight picture for the user.
This product is a factory replacement and it is perfectly designed to fit the P320 RXP X-SERIES Stainless Steel slide assembly, accommodating both the X-SERIES and non-X-SERIES Compact size grip modules. The slide assembly has been conveniently built to accommodate a 3.6 barrel, which is sold separately.
