Colt M1900
The Colt Model 1900 is a short-recoil operated "self-loading", or semi-automatic .38 caliber handgun introduced by Colt's Manufacturing Company at the turn of the 20th century. The M1900 was the first firearm to be chambered in .38 ACP (not to be confused with the shorter-cased .380 ACP) and was the first handgun to utilize short-recoil operation. The M1900 was developed from John M. Browning's earlier prototypes in the late 1890s. The United States military tested the design against other semiautomatic pistols by European makers, and adopted some versions for trial use. The M1900 and variants were also offered commercially. Variants included the Model 1902 Sporting, Model 1902 Military, Model 1903 Pocket (only in .38 ACP models; the .32 ACP model was a different design), and the Model 1905, which introduced the .45 ACP cartridge. Starting in 1909, new designs removed the front barrel link, which was replaced with a simple bushing. These designs evolved into the related M1 ...

Semi-automatic Pistol
A semi-automatic pistol (also called a self-loading pistol, autopistol, or autoloading pistol) is a repeating firearm, repeating handgun that automatically ejects and loads cartridge (firearms), cartridges in its chamber (firearms), chamber after every shot fired, but only one round of ammunition is fired each time the Trigger (firearms), trigger is pulled. The pistol's fire control group disconnects the trigger mechanism from the firing pin/striker until the trigger has been released and reset manually, unlike the self-cycled firing mechanism in machine pistol, fully automatic pistols. A semi-automatic pistol recycles part of the energy released by the propellant combustion to move its bolt (firearm), bolt, which is usually housed inside the pistol slide, 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 (firearms), hammer/striker is cocked by the slide/bolt movement, and a ...

Bolt (firearms)
Bolt from a Karabiner 98k bolt-action rifle. Note the curved handle on the side for manual operation thumb"> Slide locked back on a Desert Eagle pistol, showing the gas-operated rotating bolt mechanism A bolt is the part of a repeating, breechloading firearm that blocks the rear opening (breech) of the barrel chamber while the propellant burns, and moves back and forward to facilitate loading/unloading of cartridges from the magazine. The firing pin and extractor are often integral parts of the bolt. The terms " breechblock" and "bolt" are often used interchangeably or without a clear distinction, though usually, a bolt is a type of breechblock that has a nominally circular cross-section. In most automatic firearms that use delayed blowback, recoil, or gas operation, the bolt itself is housed within the larger bolt carrier group (BCG), which contains additional parts that receives rearward push from a gas tube ( direct impingement) or a gas piston (short-stroke o ...

40 S&W
The .40 S&W (10.2×22mm) is a Rim (firearms), rimless pistol Cartridge (firearms), cartridge developed jointly by American firearms manufacturers Smith & Wesson and U.S. Repeating Arms Company, Winchester in 1990. The .40 S&W was developed as a law enforcement cartridge designed to duplicate performance of the Federal Bureau of Investigation's (FBI) reduced-velocity 10mm Auto cartridge which could be retrofitted into medium-frame (9 mm size) semi-automatic handguns. It uses bullets ranging in weight from .''Hornady Handbook of Cartridge Reloading'', Fourth Edition (1991), pp. 593–595 History In the aftermath of the 1986 FBI Miami shootout, in which two FBI special agents were killed and five wounded, the FBI started the process of testing 9×19mm Parabellum and .45 ACP ammunition in preparation to replace its standard-issue revolver with a semi-automatic pistol. The semi-automatic pistol offered two advantages over the revolver: increased ammunition capacity and increased e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
45 Colt
The .45 Colt (11.43×33mmR), often called the .45 Long Colt, is a rimmed straight-walled, centerfire handgun cartridge dating to 1872. It was originally a black-powder revolver round developed for the Colt Single Action Army revolver. This cartridge was adopted by the U.S. Army in 1873 and served as an official US military handgun cartridge for 19 years, before being replaced by the .38 Long Colt in 1892. Although there has never been a ".45 Short Colt" cartridge, the .45 Colt is frequently called the ".45 Long Colt" (.45 LC) to better distinguish it from the shorter and less powerful .45 Schofield cartridge, which was also in use around the same time as the .45 Colt. History The .45 Colt was a joint development between Colt's Patent Firearms Manufacturing Company (now known as Colt's Manufacturing Company), of Hartford, Connecticut, and the Union Metallic Cartridge Company (UMC) of Bridgeport, Connecticut. Colt began work on the revolver in 1871, and submitted a sample to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philippine–American War
The Philippine–American War, known alternatively as the Philippine Insurrection, Filipino–American War, or Tagalog Insurgency, emerged following the conclusion of the Spanish–American War in December 1898 when the United States annexed the Philippine Islands under the Treaty of Paris (1898), Treaty of Paris. Philippine nationalists constituted the First Philippine Republic in January 1899, seven months after signing the Philippine Declaration of Independence. The United States did not recognize either event as legitimate, and tensions escalated until fighting commenced on February 4, 1899, in the Battle of Manila (1899), Battle of Manila. Shortly after being denied a request for an armistice, the Philippine Council of Government issued a proclamation on June 2, 1899, urging the people to continue the war. Philippine forces initially attempted to engage U.S. forces conventionally but transitioned to guerrilla tactics by November 1899. Philippine President Emilio Aguinaldo w ...

Revolver
A revolver is a repeating handgun with at least one barrel and a revolving cylinder containing multiple chambers (each holding a single cartridge) for firing. Because most revolver models hold six cartridges before needing to be reloaded, revolvers are commonly called six shooters or sixguns. Due to their rotating cylinder mechanism, they may also be called wheel guns. 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. 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 firearms that had to be reloaded after each shot. The hammer cocking in nearly all revolvers is manually driven and can be cocked either by the user using the thumb to directly pull back the hammer (as in single-action), or via internal linkage relaying t ...

38 Long Colt
The .38 Long Colt, also known as .38 LC, is a black powder centerfire Cartridge (firearms), cartridge introduced by Colt's Manufacturing Company in 1875. In 1892, it was adopted as a standard military pistol cartridge by the United States Army for the Colt M1892 revolver. The metric designation for the .38 Long Colt is 9.1×26mm. It is slightly more powerful than the .38 Short Colt, also known as .38 SC. The original .38 SC and .38 LC differ in case length, bullet diameter, weight, and design and are not interchangeable; however, modern production .38 SC ammunition is now loaded with a smaller, internally-lubricated bullet which can be fired from firearms chambered in .38 LC or .38 Special. The ''modern'' .38 LC can be fired from a .38 Special firearm, but not from a firearm designed for the .38 SC, since the case length is too long. Design and ballistics The .38 Long Colt's predecessor, the .38 Short Colt, used a heeled bullet of at a nominal , producing muzzle energy. The cy ...

357 Magnum
The .357 Smith & Wesson Magnum, .357 S&W Magnum, .357 Magnum, or 9×33mmR (as it is known in unofficial metric designation) is a smokeless powder cartridge with a bullet diameter. It was created by Elmer Keith, Phillip B. Sharpe, and Douglas B. Wesson of firearm manufacturers Smith & Wesson and Winchester. The .357 Magnum cartridge is notable for its highly effective terminal ballistics. The .357 Magnum cartridge is based upon Smith & Wesson's earlier .38 Special cartridge. It was introduced in 1935, and its use has since become widespread. Design The .357 Magnum was collaboratively developed over a period in the early to mid-1930s by a group of individuals as a direct response to Colt's .38 Super Automatic. At the time, the .38 Super was the only American pistol cartridge capable of defeating automobile cover and the early ballistic vests that were just beginning to emerge in the Interwar period. Tests at the time revealed that those vests defeated any handgun bullet trav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heeled Bullet
A heeled bullet is a bullet that is necked down at its base to allow a projectile the full internal diameter of a gun barrel to fit in a cartridge case of the same or narrower dimension. Heeled bullets mostly disappeared with the advent of smokeless powder cartridges, though older rimfire designs, such as the .22 caliber cartridges, still use heeled bullets, and many cartridges that date back to the black powder era still reflect their heeled bullet origins in their caliber designations. More powerful smokeless powder allowed the use of smaller, non-heeled projectiles in existing caliber guns. Two examples are a ".38 caliber" firearm actually shooting bullets of diameter, and a ".44 caliber" bullets of diameter. This legacy of historic heeled bullets is the cause of confusion among many shooting enthusiasts over the actual physical diameters of the bullets they fire. Reasons for change The heeled bullet design has many advantages, mainly when coupled with the straight or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
