XS Big Dot Sights. I have had these on my 26 and on my 19 and have decided to just change all three to the same sight pattern. These XS sights are dated 2009 they are bright. There are a few marks where I let a local shop attempt to swap them over for me. "Gunsmith" assured me could swap them over. Called me to tell me they were too tight. There are light scratches where he grabbed them with pliers. Sights are not damaged simply barely cosmetic. Will take plenty of pics. $60 Shipped UPS ground. XS Sight Systems - Home
