I'm looking for some used replacement sights for my Glock 22. I can't stand the rear stock sight and I'm looking for something with dots in the back end. I'd prefer something thats sloped but I'm not super picky. White dot, night sights, fiber sights, whatever. Just something used and cheap. Have some old night sights thats are starting to dim? I'd even be interested in those as this guns not a carry piece and for target only. Thanks.
