Sighting is fast and precise with a red fiber-optic front blade paired to an adjustable rear sight that uses two green fiber elements. This setup provides a bright sight picture in a variety of lighting conditions.

Its striker-fired, short-recoil, locked-breech design is paired with Glock's Safe Action system and trigger safety. The slide wears a durable nitrocarburized finish, and the pistol bears "MADE IN AUSTRIA / GLOCK, INC., SMYRNA, GA., AUSTRIA" slide markings.
