John Moses Browning was an American firearm designer who developed many varieties of military and civilian firearms, cartridges, and gun mechanisms, many of which are still in use around the world. He made his first firearm at age 13 in his father's gun shop and was awarded the first of his 128 firearm patents on October 7, 1879, at the age of 24. He is regarded as one of the most successful firearms designers of the 19th and 20th centuries and a pioneer of modern repeating, semi-automatic, and automatic firearms.
The Colt M1911 is a single-action, recoil-operated, semi-automatic pistol chambered for the .45 ACP cartridge. The pistol's formal U.S. military designation as of 1940 was Automatic Pistol, Caliber .45, M1911 for the original model adopted in March 1911, and Automatic Pistol, Caliber .45, M1911A1 for the improved M1911A1 model which entered service in 1926. The designation changed to Pistol, Caliber .45, Automatic, M1911A1 in the Vietnam War era.
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 .45 ACP, also known as .45 Auto, .45 Automatic, or 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 cartridge.
The Heckler & Koch MK 23, MK 23 MOD 0, Mark 23, or USSOCOM MARK 23 is a semi-automatic large-frame pistol chambered in .45 ACP, designed specifically to be an offensive pistol. The USSOCOM version of the MK23 came paired with a laser aiming module (LAM) and suppressor. The USSOCOM MK23 was adopted by the United States Special Operations Command (USSOCOM) for special operations units, beating out the nearest competitor, Colt's OHWS. Development of the pistol began in 1991 as special operations representatives identified the need for an "Offensive Handgun Weapons System—Special Operations Peculiar", and delivery of the pistols began in May 1996 to the special operation units.
The .38 Super, also known as .38 Super Auto, .38 Super Automatic, .38 Super Automatic +P , .38 Super +P , or 9×23mmSR, is a pistol cartridge that fires a 0.356-inch-diameter (9.04 mm) bullet. It was introduced in the late 1920s as a higher pressure loading of the .38 ACP, also known as .38 Auto. The older .38 ACP cartridge propels a 130-grain (8.4 g) bullet at 1,050 ft/s (320.0 m/s), whereas the .38 Super pushes the same bullet at 1,280 ft/s (390.1 m/s). The .38 Super has gained distinction as the caliber of choice for many top practical shooting competitors; it remains one of the dominant calibers in IPSC competition.
The Remington Model 51 is a small pocket pistol designed by John Pedersen and manufactured by Remington Arms in the early 20th century for the American civilian market. Remington manufactured approximately 65,000 Model 51 pistols in .32 ACP and .380 ACP calibers from 1918 to 1926, though small numbers were assembled into the mid-1930s.
The AMT Hardballer is a series of pistols that are part of the 1911 platform made by Arcadia Machine & Tool (AMT) from 1977 to 2002. The Hardballer was the first entirely stainless steel 1911 pattern pistol. Other features included adjustable rear sights and a lengthened grip safety.
The M15 General Officers is a .45 ACP pistol developed by the U.S. Army's Rock Island Arsenal from stock M1911 pistols as a replacement for the aging Colt Model 1903 and Model 1908 Pocket Hammerless pistols. The pistol was issued to United States Army general officers as a personal weapon.
The M1917 Revolvers were six-shot, .45 ACP, large frame double action revolvers adopted by the United States Military in 1917, to supplement the standard M1911 pistol during World War I. There were two variations of the M1917, one made by Colt and the other by Smith & Wesson. They used moon-clips to hold the cartridges in position, facilitate reloading, and to aid in extraction since revolvers had been designed to eject rimmed cartridges and .45 ACP rounds were rimless for use with the magazine-fed M1911. After World War I, they gained a strong following among civilian shooters. A commercial rimmed cartridge, the .45 Auto Rim, was also developed, so M1917 revolvers could eject cartridge cases without using moon-clips.
The .38 ACP, also known as the .38 Auto, .38 Automatic, or 9×23mmSR, is a semi-rimmed pistol cartridge that was introduced at the turn of the 20th century for the John Browning-designed Colt M1900. It was first used in Colt's Model 1897 prototype, which he did not produce. The metric designation for the round is 9×23mm SR (semi-rimmed), which is not to be confused with other 9×23mm cartridges.
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 and was the first handgun to utilize short-recoil operation.
The Colt Commander is a single-action, semi-automatic, magazine-fed, and recoil-operated handgun based on the John M. Browning–designed M1911. It was the first mass-produced American pistol with an aluminium alloy frame and the first Colt pistol to be chambered in 9mm Parabellum.
The Grizzly Win Mag pistols were conceived, invented, designed, engineered and developed in the 1980s by the sole inventor, Perry Arnett, who licensed his patent for an interchangeable caliber semi-automatic pistol to L.A.R. Manufacturing Inc. Perry Arnett's designs were initially flawed and were improved upon by Heinz Augat. The L.A.R. Grizzly was the most powerful semi-automatic pistol ever commercially produced after the Desert Eagle.
The Colt Double Eagle is a double-action / single action, semi-automatic pistol manufactured by Colt's Manufacturing Company between 1989 and 1997. It was available in standard full-size, as well as in more compact versions. It featured a decocking lever, and was chambered for several calibers. The family of models was known as the Series 90.
The MEU(SOC) pistol, officially designated the M45 MEUSOC, is a magazine-fed, recoil-operated, single-action, semiautomatic pistol chambered for the .45 ACP cartridge. It is a variant of the M1911 for use by the Force Recon Element of the United States Marine Corps' Marine Expeditionary Units from 1985 until 2022. It is assigned NATO Stock Number 1005-01-370-7353.
A handgun is a firearm designed to be usable with only one hand. It is distinguished from a long barreled 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.
SIG Sauer of Newington, New Hampshire, manufactures a full line of 1911 styled handguns. The earliest models were very faithful to the John M. Browning designed Colt M1911 Pistol which became the United States standard sidearm and served in that capacity for some seven decades before being replaced by the Beretta M9 handgun.
The Guncrafter Industries Model No. 1 is a variant of the widely popular M1911 handgun, modified for the .50 GI cartridge. John Browning's 1911 .45 ACP has been used for many cartridges over the past century. In every instance the cartridge used a bullet with a diameter that was the same or smaller than the original .451". Both the Desert Eagle and the LAR Grizzly have been offered in cartridges of .50 caliber. Both are large cartridges requiring a large, heavy pistol.
The Colt New Service is a large frame, large caliber, double-action revolver made by Colt from 1898 until 1941. Made in various calibers, the .45 Colt version with a 5½" barrel, was adopted by the U.S. Armed Forces as the Model 1909.
