WTS XS Big Dot Tritium Sights for Glock 17,19,22,24,26,27,31,36,38. Original packaging with instructions, installation tools, adhesive. I had em on my G19 for about a month, and they were removed without any damage to them. Prefer FTF so you can see them before you decide if you want to buy them. $90 OBO. I'm in Lake County.
