A rear sight assembly for a firearm is disclosed. The rear sight assembly contain a sight base coupled with the firearm, a sight blade pivotally coupled with the sight base and a tension member positioned between the sight base and the sight blade and configured to push the sight blade against the firearm.

An open sight for use on weapons such as handguns is introduced. The open sight features two rear aiming marks which are illuminated by an artificial light source mounted in the rear sight. A third aiming mark in the front sight is illuminated by a forward-facing light source also mounted in the rear sight. The front sight is dimensioned to substantially block the forward directed beam to reduce the visibility of the illumination forward of the weapon.
