The defining characteristic is an extended portion of the frame that runs along the entire length of the pistol’s slide. This extension offers structural reinforcement and provides a more substantial contact area between the frame and the slide. An example would be a custom-built pistol, often used in competitive shooting, where precise alignment and recoil management are critical, showcasing this design feature.
The adoption of this feature often enhances the pistol’s accuracy and durability. The added weight at the front of the weapon helps mitigate muzzle flip, improving control during rapid firing sequences. Historically, modifications like this were often implemented by gunsmiths seeking to optimize performance in specific shooting disciplines, reflecting a demand for increased stability and reduced recoil.
