Abstract: A firearm such as a pistol, which uses “iron sights”. The forward sight element is secured to a forward portion of the pistol and has a generally rectangular cross section. The rear sight has a left element and a right element, both of which are secured to the pistol at a rearward portion of the firearm. To assist the user in sighting when the forward sight may appear larger than the gap between the rear sight elements, the rear sight elements each have a profile in which they are narrower at a base near the pistol than at the sighting gap distal from the pistol.
