Glock sights.

By the way- to anyone interested, I highly suggest the Trijicon HD sights with the yellow front. Best sights I've ever put on a pistol. Beyond that, anyone could install them at home. If you have trouble, I'll even put them on for you- for free! The big U notch rear combined with the highlighted front gives a superb sight picture, especially for aging eyes like mine.
