Schüler Reform
The Reform Pistole, better known today as the Schüler Reform, is a .25 ACP semi-automatic pistol designed by August Schüler, patented in 1904. It was produced between 1907 and 1914 at his factory in Suhl, August Schüler Waffenfabrik, as well as some licensed production at other factories. It is sometimes known as the Breveté, due to stamping on the magazine referring to "patented", or D.R.P 177023, its patent number. The Reform is a unique attempt to reduce the bulk of a traditional trigger (firearms)#Double-action only, double-action revolver. It replaces the Cylinder (firearms), cylinder with a Magazine (firearms), magazine-like block of four chambers and barrels arranged vertically. Each barrel holds one cartridge, and the entire assembly is slid down into the frame of the pistol, not unlike the Clip (firearms), clip seen on a top-load bolt action rifle. When loading the magazine, the uppermost barrel stops slightly below the hammer. The friction provided by a small spring-loa ...

25 ACP
The .25 ACP (Automatic Colt Pistol) (6.35×16mmSR) is a semi-rimmed, straight-walled centerfire pistol cartridge introduced by John Browning in 1905 alongside the Fabrique Nationale M1905 pistol. Design The cartridge is of semi-rimmed design meaning that the rim protrudes slightly beyond the diameter of the base of the cartridge so the cartridge can headspace on the rim.*Wilson, R. K. ''Textbook of Automatic Pistols''. Plantersville, SC: Small Arms Technical Publishing Company, 1943. p. 258. . Though the .25 ACP was designed for semi-automatic pistols, various .25 ACP revolvers were produced in the early twentieth century by Belgian, French, and German gunmakers such as Adolph Frank and Decker. In the late twentieth century, Bowen Classic Arms produced a custom Smith & Wesson revolver in .25 ACP.Bowen, Hamilton. ''The Custom Revolver''. Privately printed, 2001. . Performance The use of the .25 ACP allows for a very compact lightweight gun, usually pocket pistols, but the ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semi-automatic Pistol
A semi-automatic pistol is a type of repeating single-chamber handgun ( pistol) that automatically cycles its action to insert the subsequent cartridge into the chamber (self-loading), but requires manual actuation of the trigger to actually discharge the following shot. As a result, 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. Additional terms sometimes used as synonyms for a semi-automatic pistol are self-loading pistol, autopistol, autoloading pistol, and automatic pistol (E.G.: Automatic Colt Pistol). A semi-automatic pistol recycles part of the energy released by the propellant combustion to move its bolt, which is usually housed inside the slide. After a round of ammunition is fired, the spent cartridge casing is extracted and ejected as the slide/bolt moves rearwards under recoil, the hammer/s ...

Suhl
Suhl () is a city in Thuringia, Germany, located SW of Erfurt, NE of Würzburg and N of Nuremberg. With its 37,000 inhabitants, it is the smallest of the six urban districts within Thuringia. Together with its northern neighbour-town Zella-Mehlis, Suhl forms the largest urban area in the Thuringian Forest with a population of 46,000. The region around Suhl is marked by up to 1,000-meter-high mountains, including Thuringia's highest peak, the Großer Beerberg (983 m), approximately NE of the city centre. Suhl was first mentioned in 1318 and stayed a small mining and metalworking town, until industrialization broke through in late 19th century and Suhl became a centre of Germany's arms production, specialized on rifles and guns with companies such as Sauer & Sohn. Furthermore, the engineering industry was based in Suhl with Simson (company), Simson, a famous car and moped producer. In 1952, Suhl became one of East Germany's 14 district capitals, which led to a government-dire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trigger (firearms)
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. Most triggers use a small flattened lever (called the ''trigger blade'') depressed by the index finger, but some weapons such as the M2 Browning machine gun or the Iron Horse TOR ("thumb-operated receiver") use a push-button-like thumb-actuated trigger design, and others like the Springfield Armory M6 Scout use a squeeze-bar trigger similar to the "ticklers" on medieval European crossbows. Although the word "trigger" technically implies the entire mechanism (known as the ''trigger group''), colloquially it is usually used to refer specifically to the trigger blade. Most firearm triggers are "single-action", meaning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Revolver
A revolver (also called a wheel gun) is a repeating handgun that has at least one barrel and uses a revolving cylinder containing multiple chambers (each holding a single cartridge) for firing. Because most revolver models hold up to six rounds of cartridge before needing to reload, revolvers are also commonly called six shooters. Before firing, cocking the revolver's hammer partially rotates the cylinder, indexing one of the cylinder chambers into alignment with the barrel, allowing the bullet to be fired through the bore. The hammer cocking in nearly all revolvers are manually driven, and can be achieved either by the user using the thumb to directly pull back the hammer (as in single-action), via internal linkage relaying the force of the trigger-pull (as in double-action), or both (as in double/single-action). By sequentially rotating through each chamber, the revolver allows the user to fire multiple times until having to reload the gun, unlike older single-shot fir ...

Cylinder (firearms)
In firearms, the cylinder is the cylindrical, rotating part of a revolver containing multiple chamber (firearms), chambers, each of which is capable of holding a single cartridge (firearms), cartridge. The cylinder rotates (revolves) around a central axis in the revolver's action (firearms), action to sequentially align each individual chamber with the gun barrel#Bore, barrel bore for repeated firing. Each time the gun is cocked, the cylinder indexing (motion), indexes by one chamber (for five-shooters, by 72Degree (angle), °, for six-shooters, by 60Degree (angle), °, for seven-shooters, by 51.43Degree (angle), °, for eight-shooters, by 45Degree (angle), °, for nine-shooters, by 40Degree (angle), °, and for ten-shooters, by 36Degree (angle), °). Serving the same function as a rotary magazine, the cylinder stores ammunitions within the revolver and allows it to repeating firearm, fire multiple times before needing to reload. Typically revolver cylinders are designed to gene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magazine (firearms)
A magazine is an ammunition storage and feeding device for a repeating firearm, either integral within the gun (internal/fixed magazine) or externally attached (detachable magazine). The magazine functions by holding several cartridges within itself and sequentially pushing each one into a position where it may be readily loaded into the barrel chamber by the firearm's moving action. The detachable magazine is sometimes colloquially referred to as a " clip", although this is technically inaccurate since a clip is actually an accessory device used to help load ammunition into a magazine. Magazines come in many shapes and sizes, from tubular magazines on lever-action and pump-action firearms that may tandemly hold several rounds, to detachable box and drum magazines for automatic rifles and light machine guns that may hold more than one hundred rounds. Various jurisdictions ban what they define as "high-capacity magazines". Nomenclature With the increased use of semi-au ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clip (firearms)
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 ('loose rounds'). There are several types, most made of inexpensive stamped sheet metal, intended to be disposable, though they are often re-used. Types Stripper A stripper clip (US) or charger (UK) is a speedloader that holds several cartridges as a unit for easier loading into a firearm's internal magazine. After the bolt is opened and the stripper clip is placed in position (generally in a slot on the receiver or bolt), the cartridges are pressed down, removing or 'stripping' them off the clip and into the magazine. The clip is then either removed and tossed away, or the bolt is thrown forward, expelling the clip automatically. However, some weapons, such as the Mosin–Nagant require the operator to manually remove the empt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bolt Action
Bolt-action is a type of manual firearm action that is operated by ''directly'' manipulating the bolt via a bolt handle, which is most commonly placed on the right-hand side of the weapon (as most users are right-handed). Most bolt-action firearms use a rotating bolt design, where the handle must first be rotated upward to unlock the bolt from the receiver, then pulled back to open the breech and allowing any spent cartridge case to be extracted and ejected. This also cocks the striker within the bolt (either on opening or closing of the bolt depending on the gun design) and engages it against the sear. When the bolt is returned to the forward position, a new cartridge (if available) is pushed out of the magazine and into the barrel chamber, and finally the breech is closed tight by rotating the handle down so the bolt head relocks on the receiver. Bolt-action firearms are generally repeating firearms, but some single-shot breechloaders also use bolt-action design as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rack And Pinion
A rack and pinion is a type of linear actuator that comprises a circular gear (the '' pinion'') engaging a linear gear (the ''rack''). Together, they convert rotational motion into linear motion. Rotating the pinion causes the rack to be driven in a line. Conversely, moving the rack linearly will cause the pinion to rotate. A rack and pinion drive can use both straight and helical gears. Though some suggest helical gears are quieter in operation, no hard evidence supports this theory. Helical racks, while being more affordable, have proven to increase side torque on the datums, increasing operating temperature leading to premature wear. Straight racks require a lower driving force and offer increased torque and speed per percentage of gear ratio which allows lower operating temperature and lessens viscal friction and energy use. The maximum force that can be transmitted in a rack and pinion mechanism is determined by the tooth pitch and the size of the pinion as well as the gear ...

Hammer (firearms)
The hammer is a part of a firearm that is used to strike the percussion cap/primer, or a separate firing pin, to ignite the propellant and fire the projectile. It is so called due to the fact that it resembles a hammer in both form and function. The hammer itself is a metal piece that forcefully rotates about a pivot point. Evolution Firearms, initially known as "hand cannons", first became a viable weapon in 1364 through the advancement of chemical technologies to create a gunpowder efficient enough to launch a projectile at high speeds in a hand-held weapon. The issue quickly arose of how to effectively ignite the gunpowder while maintaining the weapon’s aim at the target. Initially, the problem was solved by using a "slow match": a chemically treated piece of rope that would stay lit for an extended period of time. The smoldering end of the rope would then be manually brought into contact with the gunpowder through a touch hole in the barrel of the weapon. when the user ...
