An adjustable sight adapted for mounting on a pistol having a transverse dovetail slot, said adjustable sight assembly comprising:
- a base, said base having a base front surface, with at least a lower portion of said base front surface defining a substantially planar base lower front surface terminating in a substantially linear base front edge, said base being adapted to be received in said transverse dovetail slot;
- a substantially planar base bottom surface, said planar base bottom surface terminating at said linear front edge and cooperating with said planar base lower front surface to define a selected base front edge angle less than 90° and complementary to said transverse dovetail slot;
- a first base side wall projecting upwardly from said planar base bottom surface and a second base side wall projecting upwardly from said planar base bottom surface and spaced from said first base side wall in the direction of the transverse dovetail;
- a substantially planar base top surface opposite said planar base bottom surface, said first and second spaced base side walls projecting upwardly from said base top surface to define substantially parallel opposing first and second spaced base side wall surfaces;
- a base side wall upper beveled surface of each said first and second spaced base side walls;
- a first bore in said first base side wall, said first bore having a first bore axis aligned with said base front edge;
- a second bore in said second base side wall, said second bore having a second bore axis aligned with said base front edge and being coaxially aligned with said first bore, said first bore axis and said second bore axis being spaced within five millimeters of said base front edge;
- a vertical tilt member having a vertical tile member front edge and a vertical tilt member rear edge and including a vertical tilt member hinge bore proximate said vertical tilt member front edge;
- said vertical tile member carrying a sighting notch, said sighting notch being positioned proximate said tilt member rear edge;
- vertical tilt member beveled upper surfaces, said vertical tilt member beveled upper surfaces including a forward portion aligned with said base side wall upper beveled surfaces;
- an elevation tilt hinge pin securing said vertical tilt member between said first base side wall and said second base side wall, said vertical tilt member hinge bore being aligned with said first base side wall bore and said second base side wall bore, said elevation tilt hinge pin passing through said vertical tilt member hinge bore and said first and second base side wall bores to provide a tilting motion of said vertical tilt member about said base to allow said sighting notch to move through an arc having a selected vertical range;
- and
- a horizontally translatable slide member at said rear edge of said vertical tilt member, said horizontally translatable slide member including said sighting notch and having slide member beveled upper side surfaces, said vertical tilt member beveled upper surfaces including rearward portions aligned with said slide member beveled upper side surfaces, said aligned base side wall upper beveled surfaces, said vertical tilt member beveled upper forward portion, said vertical tilt member beveled upper surface rearward portions, and said slide member beveled upper side surfaces cooperating to define a smooth, snag-resistant upper overall surface of said adjustable sight assembly having an overall length of not greater than 30 mm.
