Heckler & Koch GmbH is a German firearms manufacturer that produces handguns, rifles, submachine guns, and grenade launchers. The company is located in Oberndorf am Neckar, Baden-Württemberg, and also has subsidiaries in the United Kingdom, France, and the United States.
A submachine gun (SMG) is a magazine-fed automatic carbine designed to fire handgun cartridges. The term "submachine gun" was coined by John T. Thompson, the inventor of the Thompson submachine gun, to describe its design concept as an automatic firearm with notably less firepower than a machine gun. As a machine gun must fire rifle cartridges to be classified as such, submachine guns are not considered machine guns.
A semi-automatic rifle is an autoloading rifle that fires a single cartridge with each pull of the trigger and uses part of the fired cartridge's energy to eject the case and load another cartridge into the chamber. In contrast, a bolt-action rifle requires the user to cycle the bolt manually before they can fire a second time, and a fully automatic rifle fires continuously until the trigger is released.
Mauser, originally the Königlich Württembergische Gewehrfabrik, was a German arms manufacturer. Their line of bolt-action rifles and semi-automatic pistols was produced beginning in the 1870s for the German armed forces. In the late 19th and early 20th centuries, Mauser designs were also exported and licensed to many countries, which adopted them as military and civilian sporting firearms. The Gewehr 98 in particular was widely adopted and copied, and it is the foundation of many of today's sporting bolt-action rifles.
The Gewehr 43 or Karabiner 43 is a 7.92×57mm Mauser caliber semi-automatic rifle developed by Germany during World War II. The design was based on that of the earlier G41(W) but incorporated an improved short-stroke piston gas system similar to that of the Soviet SVT-40.
Carl Walther GmbH Sportwaffen, or simply known as Walther, is a German firearm manufacturer, and a subsidiary of the PW Group. Founded by Carl Walther in 1886, the company has manufactured firearms and air guns at its facility in Germany for more than 100 years. Walther Arms, Inc. is the United States Walther business unit and is based in Fort Smith, Arkansas.
A semi-automatic pistol is a handgun that automatically ejects and loads cartridges in its chamber after every shot fired. Only one round of ammunition is fired each time the trigger is pulled, as the pistol's fire control group disconnects the trigger mechanism from the firing pin/striker until the trigger has been released and reset.
The Walther PP series pistols are blowback-operated semi-automatic pistols, developed by the German arms manufacturer Carl Walther GmbH Sportwaffen.
Blowback is a system of operation for self-loading firearms that obtains energy from the motion of the cartridge case as it is pushed to the rear by expanding gas created by the ignition of the propellant charge.
The Walther P38 is a 9 mm semi-automatic pistol that was developed by Carl Walther GmbH as the service pistol of the Wehrmacht at the beginning of World War II. It was intended to replace the comparatively complex and expensive to produce Luger P08. Moving the production lines to the more easily mass producible P38 once World War II started took longer than expected, leading to the P08 remaining in production until September 1942 and copies remained in service until the end of the war.
The 9×19mm MP 3008 was a German last ditch submachine gun manufactured towards the end of World War II in early 1945.
Ferdinand Ritter von Mannlicher was an Austrian engineer and small arms designer. Along with James Paris Lee, Mannlicher was particularly noted for inventing the en-bloc clip charger-loading box magazine system. Later, while making improvements to other inventors' prototype designs for rotary-feed magazines, Mannlicher, together with his protégé Otto Schönauer, patented a perfected rotary magazine design, the Mannlicher–Schönauer rifle, which was a commercial and military success.
The Steyr GB is a double-action 9×19mm Parabellum caliber, large-framed semi-automatic pistol employing a gas-delayed blowback action. As such the GB abbreviation stands for Gasbremse. It was designed in 1968, intended as a replacement for older handguns in Austrian military service.
J. P. Sauer und Sohn GmbH is a manufacturer of firearms and machinery and is the oldest firearms manufacturer still active in Germany. The products of this company are frequently referred to as Sauer.
The Volkssturmgewehr is the name of several rifle designs developed by Nazi Germany during the last months of World War II. They share the common characteristic of being greatly simplified as an attempt to cope with severe lack of resources and industrial capacity in Germany during the final period of the war. The Volkspistole was a partner program, almost identical, but for pistols instead.
The StG 45(M) (abbreviation of Sturmgewehr 45, "Assault Rifle 45") sometimes referred to as the MP 45(M), was a prototype assault rifle developed by Mauser for the Wehrmacht at the end of World War II, using an innovative roller-delayed blowback operating system. It fired the 7.92×33mm Kurz (or "Pistolenpatrone 7.9mm") intermediate cartridge at a cyclic rate of around 450 rounds per minute.
The Carabinetta Automatica O.V.P was a submachine gun developed in Italy.
The 7.92×33mm Kurz is a rimless bottlenecked intermediate rifle cartridge developed in Nazi Germany prior to and during World War II, specifically intended for development of the Sturmgewehr 44. The ammunition is also referred to as 7.9mm Kurz, 7.9 Kurz, 7.9mmK, or 8×33 Polte. The round was developed as a compromise between the longer 7.92×57mm full-power rifle cartridge and the 9×19mm Parabellum pistol cartridge.
Flapper locking is a type of locking mechanism used in self-loading firearms. It involves a pair of flappers on the sides of the bolt that each lock into an outwards recess in the receiver as the bolt is in battery. As the bolt is forced backwards after the firing of a cartridge, the flappers recede back into the bolt, therefore unlocking and sending the bolt backwards to cycle the gun. The design was patented in 1870 by Lieutenant Friberg of the Swedish Army, but the first actual example of a firearm that used this was made by another Swedish man named Kjellman in 1907. Most use of flapper locking came from the designs of the Soviet Union's Vasily Degtyaryov in the years surrounding World War II.
