Great sights from a great company - XS Sight Systems DXW Big Dot Sight - Sig Sauer

I’ve been eyeballing these sights for awhile. I finally pulled the trigger when my stock night sights got banged up and my LGS has them for a good price with free install. Took them to the range today and shot better than with 3 dot sights. While shooting rapid fire the white insert popped out. I called XS and the only questions they asked was where to ship the new front sight. Apparently there was a vendor mess up and some product got out to the customers. Also in regards to no tritium line on the back. It really isn’t a big deal. I actually like it better than the tritium line. Super simple at night. Put the dot on the target.
