INA Model 953
The INA Model 953 is Brazilian submachine gun - a modified Madsen M/50. It was manufactured by the Indústria Nacional de Armas in São Paulo São Paulo (, ; Portuguese for ' Saint Paul') is the most populous city in Brazil, and is the capital of the state of São Paulo, the most populous and wealthiest Brazilian state, located in the country's Southeast Region. Listed by the Ga ... Brazil under license for Madsen. Production began in 1950. The first Model was marked M.B.-50 and was manufactured till 1953 and was marked with a large Brazilian crest. In late 1953 the Model 1953 was introduced. Improvements on the 1953 model were a larger magazine housing and a metal loop riveted to the lower right side of the magazine housing. The loop could then hold the magazine housing together. Also the retracting handle was changed on the Model 953 to the right side instead of the top as was the buffer spring and the shape of the extractor, ejector and the firing pin. The INA M ...

Sub Machine Gun
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 (hence the prefix " sub-"). As a machine gun must fire rifle cartridges to be classified as such, submachine guns are not considered machine guns. The submachine gun was developed during World War I (1914–1918) as a close quarter offensive weapon, mainly for trench raiding. At its peak during World War II (1939–1945), millions of SMGs were made for use by regular troops, clandestine commandos and partisans alike. After the war, new SMG designs appeared frequently.Military Small Arms Of The 20th Century. Ian Hogg & John Weeks. Krause Publications. 2000. p93 However, by the 1980s, SMG usage decreased. Today, submachine guns have been largely replaced by assault rifles, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dansk Industri Syndikat
DISA is a company founded in Denmark (with the name Compagnie Madsen A/S) which since 1900 has produced metal casting products. In 1936 it changed name from Dansk Rekyl Riffel Syndikat A/S to Dansk Industri Syndikat A/S and was a defence manufacturer most notable for producing the Madsen machine gun and Madsen M-50. History In 1879 V.H.O Madsen designed an air-cooled, repeating machine gun which then took his name, Madsen. In the year 1900 the company Compagnie Madsen A/S was founded. This company was to produce this Madsen machine gun. In 1930 A.P Møller bought a sum of shares corresponding to 15% of the total shares. In the following years A.P Møller expanded his shareholding to 31.6%, and was hereby the biggest shareholder.

Indústria Nacional De Armas
Indústria Nacional de Armas (INA) was a Brazilian firearms manufacturer. Background In April 1940, the Brazilian Army officer Plinio Cardoso was in Denmark visiting the Dansk Industri Syndicat factory on an official mission, when the Germans invaded the country. Afraid that their submachine gun designs would fall into the hands of the Wehrmacht, the company handed the designs over to Plínio, who would return to Brazil and keep the designs safely away from Europe. After the end of the war, the Brazilian officer returned to Denmark to return the designs, which began manufacturing the Madsen M-46 submachine gun soon after. In recognition of his work, the company granted him the rights to manufacture the weapon in Brazil. Some models and first prototypes of the submachine gun would have been developed and adapted inside the IMBEL factory in Itajubá, in partnership with the engineer Euclydes Bueno Filho, who would join Plinio to found INA.

45 ACP
The .45 ACP (Automatic Colt Pistol) or .45 Auto (11.43×23mm) is a rimless straight-walled handgun cartridge designed by John Moses Browning in 1904, for use in his prototype Colt semi-automatic pistol. After successful military trials, it was adopted as the standard chambering for Colt's M1911 pistol. The round was developed due to a lack of stopping power experienced in the Moro Rebellion in places like Sulu. The issued ammunition, .38 Long Colt, had proved inadequate, motivating the search for a better cartridge. This experience and the Thompson–LaGarde Tests of 1904 led the Army and the Cavalry to decide that a minimum of .45 caliber was required in a new handgun. The standard issue military .45 ACP round uses a 230-grain (14.9 g) round nose projectile that travels at approximately 830 feet per second (250 m/s) when fired from a government-issue M1911A1 pistol. It operates at a relatively low maximum chamber pressure rating of , compared to for both 9mm Parab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blowback (arms)
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. Several blowback systems exist within this broad principle of operation, each distinguished by the methods used to control bolt movement. In most actions that use blowback operation, the breech is not locked mechanically at the time of firing: the inertia of the bolt and recoil , relative to the weight of the bullet, delay opening of the breech until the bullet has left the barrel. A few locked breech designs use a form of blowback (example: primer actuation) to perform the unlocking function. The blowback principle may be considered a simplified form of gas operation, since the cartridge case behaves like a piston driven by the powder gases. Other operating principles for self-loading firearms include delayed blowback, blow forward, gas operation, and recoil operatio ...

Open Bolt
A firearm is said to fire from an open bolt if, when ready to fire, the bolt and working parts are held to the rear of the receiver, with no round in the chamber. When the trigger is actuated, the bolt travels forward, feeds a cartridge from the magazine or belt into the chamber, and fires that cartridge in the same movement. Like any other self-loading design, the action is cycled by the energy released from the propellant, which sends the bolt back to the rear, compressing the mainspring in readiness for firing the next round. In an open-bolt gun firing semi-automatically, the bolt is caught and held at this point by the sear after each shot; and in automatic open-bolt fire, it's caught and held in this manner whenever the trigger is released. In contrast to this, in closed-bolt guns the trigger and sear do not affect the movement of the bolt directly. Generally, an open-bolt firing cycle is used for fully automatic weapons and not for semi-automatic weapons (except some se ...

Madsen M/50
The Madsen M-50 or M/50 is a submachine gun introduced in 1950. It was produced by the Danish company Dansk Industri Syndikat of Copenhagen, Denmark. The company was colloquially known as ''Madsen'' after its founder Vilhelm Herman Oluf Madsen. Overview This firearm was a modified variation of the M/46. The only major improvement was the simplified retracting handle. Introduction of the M/50 occurred on November 7, 1950, at Mosede, Denmark, until 1953. The M/50 is made of stamped sheet metal. It is an open bolt design which means it fires when the bolt is in the locked back open position with a fixed firing pin. The M/46 and M/50 share a unique design: the firearm is stamped from two pieces of sheet metal which are shaped with an integral rear pistol grip and magazine housing. The two pieces fit together like a clam shell with the hinge at the rear of the pistol grip. The firearm is held together with a barrel locking nut which is threaded onto the fore section of the two recei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
