This is a one piece aluminum sight base for mounting a red dot optic to the Sig Sauer P320 X5 pistols. It uses the R1 dovetail slot to mount the sight to your slide and is bolted through the slide. Hard anodized for a long service life. .519oz with hardware, not including optic.
Due to variances in the slide cut and a required tight fit, some minor fitting may be needed to install the mount. A file is recommended for fitting.
Will also fit the P320 X-Carry.
Does NOT work with the RX or M17 P320 models.
