The Equinox® is the balance between day and night. The P220® Carry Equinox is a limited production .45ACP designed by SIG SAUER® Custom Shop master gunsmiths. It features a two-tone accented Nitron® stainless steel slide with a lightweight black hard-anodized alloy frame. The contrast in color is achieved by the brush polished flats of the slide and nickel accents. The combination of the TRUGLO® Tritium Fiber Optic front sight and the rear SIGLITE® night sight provides excellent target acquisition, whether shooting day or night. To further enhance the low-light use, the Equinox comes equipped with an accessory rail. To complete the package, the Equinox features gray laminated wood grips with a perfect blend of checkering and stippling to enhance not only the form but the function.
