Abstract
A pistol having a device to prevent ejector over-rotation is provided. The pistol includes a frame having an upper rear portion having a left side wall and a right side wall. An ejector has a first end, a second end and a pivot point. The first end has a cam surface for ejection of a spent case. The second end contacts an over-rotation stop. A sear spring is adjacent to the upper rear portion and has a cantilevered spring leg disposed adjacent to the second end of the ejector to rotably bias the ejector downward such that the first end of the ejector pivots upward. A stop is disposed between said left and right side walls to engage the second end of the ejector to limit rotational travel past the spring leg of the sear spring.
