| The Parabellum-Pistole (Pistol Parabellum), popularly (but incorrectly) known as the Luger, is a toggle locked, recoil operated, semi-automatic pistol. The design was patented by Georg J. Luger in 1898 and produced by German arms manufacturer Deutsche Waffen- und Munitionsfabriken (DWM) starting in 1900; it was an evolution of the 1893 Hugo Borchardt designed C-93. The Luger was made popular by its use by Germany during World War I and World War II. Though the Luger pistol was first introduced in 7.65x22mm Parabellum, it is notable for being the pistol for which the 9x19mm Parabellum cartridge was developed. --Design-- The Luger uses a toggle-lock action, which utilizes a jointed arm to lock, as opposed to the slide actions of almost every other semi-automatic pistol. After a round is fired, the barrel and toggle assembly (both locked together at this point) travel rearward due to recoil. After moving roughly one-half inch (13 mm) rearward, the toggle strikes a cam built into the frame, causing the knee joint to hinge and the toggle and breech assembly to unlock. At this point the barrel stops its rearward movement (it impacts the frame), but the toggle and breech assembly continue moving (bending the knee joint) due to momentum, extracting the spent casing from the chamber and ejecting it. The toggle and breech assembly subsequently travel forward (under spring tension) and the next round from the magazine is loaded into the chamber. The entire sequence occurs in a ... |
