Abstract: A light projection apparatus for projecting an illuminated line onto a surface which comprises a light source for emitting a light beam and a light beam deflection lens which is adapted to receive the emitted light beam and project a work light beam which will be visible as a straight line on the surface, the light deflection lens is configured so that the visible line on the surface is of generally equal illumination along its entire length. The light beam deflection lens preferably comprises an optical lens which is adapted to refract and reflect the emitted light beam.

Abstract: The invention concerns a handgun which comprises a trigger (42), a firing mechanism arranged to be actuated by the trigger and to fire a cartridge, a barrel (4) through which the bullet of the cartridge is projected when the cartridge is fired and a butt (60) which is arranged to be gripped in the hand of a user. The axis (57) of the barrel, and hence the line of action of a recoil force which is generated when the cartridge is fired, is at least substantially aligned with the line of action of a resisting force applied to the handgun by the use's hand. Also, the trigger is located above the axis of the barrel.
