A rigid mounting apparatus for attaaching an auxiliary sighting aid to a pistol. In one embodiment, two major shapes are utilized, one of which has a transverse cross-section that is generally U-shaped; the second shape forms an L-shaped bracket that fits below the barrel of a pistol and lies ahead of the trigger guard. In another embodiment, three elements are designed to fit in such a way that, in combination, they establish a U-shaped body for mounting a sighting aid above the barrel. Two side plates of this embodiment are configured so that they can be extruded from a common die; one of them is rotated so that the two plates form mirror images of each other when they are attached to a pistol. A bracket cooperates with some structural element on the pistol (such as the slide latch pin) to securely hold the mounting apparatus in place when the pistol is fired, so that recoil forces from firing will not cause the mounting apparatus to shift with respect to the pistol. Threaded fasteners hold the various pieces rigidly together. Adjustment screws may be used to take up any slack between the main structural parts of the mounting apparatus and the pistol's frame.
