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.

If you are looking for a plate to mount you RMR this one works very well and its inexpensive. The only reason I did not rate it a 5 was due to the little bit of filing to make it fit. This was expected as they do tell you it may need to be filed. Don't worry it's not hard to file the one side at all, just takes a few minutes with taking a little off at a time. I would just file a little and then test fit. After a few minutes it fit perfect and presto, add some screws and you are done!!
