The mark consists of the three-dimensional overall configuration of a pistol. The mark includes the overall size and shape of the pistol and the external accents and features of the pistol. The mark includes the relative proportions of the external accents and features of the pistol. The mark includes the lines on the grip that extend forward and outline the front and rear textured portions on the hand grip, the front and rear textured portions of the hand grip outlined by said curved lines, the rear-leaning angle of the hand grip, the three ridges under the muzzle comprising the equipment rail, the rounded rectangular trigger guard, the small square-like notch below and behind the trigger, the approximately rectangular takedown lever above the trigger guard that features texturing in the form of stacked horizontal ridges on its rear side, and the rectangular slide stop above the magazine release. The mark also includes the two indentations above the equipment rail and below the slide such that the frame narrows from the slide down to the equipment rail, the lengthwise indentation along the slide, the polygonal indentation at the front of the slide, the small semicircular indentation above the rear of the equipment rail, the small rectangular indentation above the takedown lever, the seven scalloped serrations indicating ridges on the surface of the slide, and the squared beavertail. The dotted lines represent the trigger, the front and rear sights and the magazine release. The matter shown in dotted lines is not part of the mark. The stippling is a feature of the mark indicating texturing and not intended to indicate color.
