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 derringer is a small handgun that is neither a revolver, semi-automatic pistol, nor machine pistol. It is not to be confused with mini-revolvers or pocket pistols, although some later derringers were manufactured with the pepperbox configuration. The modern derringer is often multi barreled, and is generally the smallest usable handgun of any given caliber and barrel length due to the lack of a moving action, which takes up more space behind the barrel. It is frequently used by women because it is easily concealable in a purse or a stocking.
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 .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 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 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.
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.
Strayer-Voigt, Inc. is a manufacturer of M1911-styled modular pistols. The Strayer-Voigt system is called modular because the lower grip and trigger guard, which is made of carbon steel, stainless steel, titanium or aluminum, is a separate component from the metal upper portion of the frame that comprises the dust cover and frame rails. They are the most famous for their Hybrid series of pistols as well as their IMM Open division pistols made for competitions. SVI markets its products under the brand name Infinity Firearms. The Infinity pistols are sometimes unofficially known by the combined name of Strayer-Voigt Infinity among some enthusiasts, a play on the SVI acronym.
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 .50 GI (12.7×23mmRB) pistol cartridge was developed by Alex Zimmermann of Guncrafter Industries. The .50 GI was introduced at the 2004 SHOT Show alongside the Guncrafter Industries Model No. 1, a variation of the M1911. The round has a rebated rim that is the same diameter as that of the .45 ACP.
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 Model 1902 is a semi-automatic pistol developed by famous American firearms designer John Browning and produced by the Colt's Patent Firearms Manufacturing Company in the early 20th century. The Model 1902 was not a new design, but rather an incremental improvement upon the nearly identical M1900, and would transition from the 1900 into three distinct but related pistols with the same action and cartridge, the 1902 Sporting Model, the 1902 Military model, and the 1903 Pocket Hammer model. The 1902 Sporting model was so similar to the 1900 that it continued the serial number range, while the 1902 Military Model featured a different serial range as did the 1903 Pocket Hammer model. The 1902 Military Model featured a square and lengthened grip frame with an additional round in the magazine, while the 1903 Pocket Hammer featured a shortened barrel and slide but retained the Sporting model grip frame. The Colt M1905 .45 ACP pistol would be derived from the same lineage, also with a different serial number range.

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.
SIG Sauer of Newington, NH United States manufactures a full line of 1911 styled handguns. The earliest models were very faithful to the John M.

The .40 Super (10.2x25mm) is a powerful automatic pistol cartridge developed through the collaboration of Fernando Coelho and Tom Burczynski and introduced by Triton Cartridge in 1996. It delivers ballistics comparable to the .41 Magnum revolver cartridge, yet functions in standard 1911s and other full-size pistols. A 5” 1911 chambered in the cartridge is capable of penetrating 46” of Clear Ballistics gel.
The Colt Officer's Model or Colt Officer's ACP is a single-action, semi-automatic, magazine-fed, and recoil-operated handgun based on the John M. Browning designed M1911. It was introduced in 1985 as a response from Colt to numerous aftermarket companies making smaller versions of the M1911 pistol.
The Arsenal Firearms AF2011-A1 is a double-barreled, semi-automatic pistol of Italian origin. The weapon is a derivative of the M1911 pistol and the majority of internal parts including the firing pins, firing pin plates, sear groups, springs, recoil rods, and mainspring housings are interchangeable with standard M1911 replacement parts. The purpose of the AF2011A1 pistol is to increase the ballistic capability of .45 ACP without the need to develop a more powerful round. The AF2011A1 has its roots in the Grieco pistol that also came with double barrels for the same purpose.
