Iron sights for the Ruger GP100. Each set is machined for the Ruger GP100 slide cut, so it seats in the correct dovetail without modification.
Choose the piece you need – a front sight, a rear sight, or a full set – and the height profile: standard, low-profile, or co-witness to align with a slide-mounted red dot.
Co-witness height lines up with an optic, not on its own; pick it only if you run a red dot on the Ruger GP100.
