The 7.65mm Roth–Sauer is a centerfire cartridge resembling a shortened .32 ACP. Two self-loading pocket pistols were designed for this cartridge. One was manufactured by Roth-Sauer of Germany, and the other by Frommer of Hungary. [1]
The Roth-Sauer pistol was named for its Austrian patentee Georg Roth, but was developed by Czech designer Karel Krnka . It was produced in small quantities (probably less than 3000) by J P Sauer & Sohn of Suhl in Germany during the early 1900s. It employed a notably complex long-recoil mechanism to fire a unique 7.65 x 13mm cartridge. It bears similarities to other designs by Krnka, the most famous of which was Roth-Steyr adopted for service by the Austro-Hungarian Army. The striker firing mechanism is also of interest, in that it foreshadows the system used in modern double-action striker-fired pistols such as the Glock.
The markings on some of the surviving pistols suggest that they were used by the Berlin police and also Landes polizei for the German colony of South West Africa. [2]
A firearm is any type of gun that uses an explosive charge and is designed to be readily carried and used by an individual. The term is legally defined further in different countries.
A semi-automatic firearm, also called a self-loading or autoloading firearm, is a repeating firearm whose action mechanism automatically loads a following round of cartridge into the chamber and prepares it for subsequent firing, but requires the shooter to manually actuate the trigger in order to discharge each shot. Typically, this involves the weapon's action utilizing the excess energy released during the preceding shot to unlock and move the bolt, extracting and ejecting the spent cartridge case from the chamber, re-cocking the firing mechanism, and loading a new cartridge into the firing chamber, all without input from the user. To fire again, however, the user must actively release the trigger, allow it to "reset", before pulling the trigger again to fire off the next round. As a result, each trigger pull only discharges a single round from a semi-automatic weapon, as opposed to a fully automatic weapon, which will shoot continuously as long as the ammunition is replete and the trigger is kept depressed.
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 .380 ACP, is a rimless, straight-walled pistol cartridge developed by firearms designer John Moses Browning. The cartridge headspaces on the mouth of the case. It was introduced in 1908 by Colt, for use in its new Colt Model 1908 pocket hammerless semi-automatic, and has been a popular self-defense cartridge ever since, seeing wide use in numerous handguns. Other names for .380 ACP include .380 Auto, 9×17mm, 9mm Browning, 9mm Corto, 9mm Kurz, 9mm Short, and 9mm Browning Court. It should not be confused with .38 ACP. The .380 ACP does not strictly conform to cartridge naming conventions, named after the diameter of the bullet, as the actual bullet diameter of the .380 ACP is .355 inches.
.32 ACP is a centerfire pistol cartridge. It is a semi-rimmed, straight-walled cartridge developed by firearms designer John Browning, initially for use in the FN M1900 semi-automatic pistol. It was introduced in 1899 by Fabrique Nationale, and is also known as the 7.65 mm Browning Short.
A firing pin or striker is a part of the firing mechanism of a firearm that impacts the primer in the base of a cartridge and causes it to fire. In firearms terminology, a striker is a particular type of firing pin where a compressed spring acts directly on the firing pin to provide the impact force rather than it being struck by a hammer.
A clip is a device that is used to store multiple rounds of ammunition together as a unit for insertion into the magazine or cylinder of a firearm. This speeds up the process by loading the firearm with several rounds at once, rather than one at a time. There are several types, most made of inexpensive stamped sheet metal, intended to be disposable, though they are often re-used.
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.
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.
In American English, a pocket pistol is any small, pocket-sized semi-automatic pistol, and is suitable for concealed carry in a pocket or a similar small space.
The Sauer 38H or often just H was a small semi-automatic pistol made in Nazi Germany from 1938 until just after the end of World War II by J. P. Sauer & Sohn, then based in Suhl, Germany. The "H" in the model number is short for "hahn", referring to the internal hammer of the firing mechanism.
A trigger is a mechanism that actuates the function of a ranged weapon such as a firearm, airgun, crossbow, or speargun. The word may also be used to describe a switch that initiates the operation of other non-shooting devices such as a trap, a power tool, or a quick release. A small amount of energy applied to the trigger leads to the release of much more energy.
A handgun is a firearm designed to be usable with only one hand. It is distinguished from a long gun which needs to be held by both hands and braced against the shoulder. Handguns have shorter effective ranges compared to long guns, and are much harder to shoot accurately. While most early handguns are single-shot pistols, the two most common types of handguns used in modern times are revolvers and semi-automatic pistols, although other handguns such as derringers and machine pistols also see infrequent usage.
A pistol is a type of handgun, characterized by a barrel with an integral chamber. The word "pistol" is derived from the Middle French pistolet, meaning a small gun or knife, and first appeared in the English language c. 1570 when early handguns were produced in Europe. In colloquial usage, the word "pistol" is often used as a generic term to describe any type of handgun, inclusive of revolvers and the pocket-sized derringers.
The Steyr M1912, also known as the Steyr-Hahn, is a semi-automatic pistol developed in 1911 by the Austrian firm Steyr Mannlicher, based on the mechanism of the Roth–Steyr M1907. It was developed for the Austro-Hungarian Army and adopted in 1912. It was the standard Austro-Hungarian military handgun of World War I. It was able to endure the adverse conditions of trench warfare during World War I.
The Roth–Steyr M1907, or, more accurately Roth-Krnka M.7 was a semi-automatic pistol issued to the Austro-Hungarian kaiserliche und königliche Armee cavalry during World War I. It was the first adoption of a semi-automatic service pistol by the army of a major military power.
The Dreyse Model 1907 is a semi-automatic pistol designed by Louis Schmeisser. The gun was named after Nikolaus von Dreyse, the designer and inventor of the Dreyse Needle Gun. The Waffenfabrik von Dreyse company was acquired by Rheinische Metallwaren & Maschinenfabrik Sömmerda in 1901, although the Dreyse Model pistols were marketed under the Dreyse name.
In firearms, a safety or safety catch is a mechanism used to help prevent the accidental discharge of a firearm, helping to ensure safer handling.
The Modelo 1905 is a pistol designed by Ferdinand Ritter von Mannlicher in 1899 and originally produced in Austria as the Mannlicher Model 1901. The Mannlicher Model 1901 was an improved version of the Model 1900, both of which were produced by Österreichische Waffenfabriks-Gesellschaft. All of these models have the same basic design and operation, but minimal adjustments were made to improve each of them. The Modelo 1905 is the version of the Model 1901 that the Argentine Army purchased from Steyr in 1905. This semi-automatic pistol has a unique and elegant appearance due to the curve of the handgrip. It is single action and uses a blowback operation system to reload. Like its predecessors, the Modelo 1905 has a non-detachable magazine that can be loaded from the top with a stripper clip.
The Mauser Model 1914 is a semi-automatic pistol made by Mauser. A derivative of the .25 caliber Model 1910 designed by Josef Nickl, it uses 32 ACP ammunition.
