50 GI
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. In 2006, Guncrafter Industries introduced its 1911 Model No. 2 which sports a full length light rail/dust cover and is chambered for the .50 GI cartridge. Both the M1 and the M2 can be fitted with Guncrafter Industries' .45 ACP conversion unit, the .45 ACP magazines hold 8 rounds. Physically, the .50 GI round is wider than the .45 ACP and slightly longer. The M1 and M2 magazines can hold seven rounds. The Glock conversion can hold eight rounds in the standard magazine and nine with the extended base pad. Performance The .50 GI operates at pressures comparable to the .45 ACP, around 15,000 psi (100 MPa). Felt recoil is not unlike that of the .45 ACP. The .50 GI has developed a r ...

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] |
Glock 21
Glock is a brand of polymer- framed, short recoil-operated, locked-breech semi-automatic pistols designed and produced by Austrian manufacturer Glock Ges.m.b.H. The firearm entered Austrian military and police service by 1982 after it was the top performer in reliability and safety tests. Glock pistols have become the company's most profitable line of products, and have been supplied to national armed forces, security agencies, and police forces in at least 48 countries. Glocks are also popular firearms among civilians for recreational and competition shooting, home- and self-defense, both in concealed or open carry. In 2020, the Glock 19 was the best selling pistol on GunBroker. History The company's founder, head engineer Gaston Glock, had no experience with firearms design or manufacture at the time their first pistol, the Glock 17, was being prototyped. Glock had extensive experience in advanced synthetic polymers, which was instrumental in the company's design of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

50 Caliber Handguns
5 (five) is a number, numeral and digit. It is the natural number, and cardinal number, following 4 and preceding 6, and is a prime number. It has attained significance throughout history in part because typical humans have five digits on each hand. In mathematics 5 is the third smallest prime number, and the second super-prime. It is the first safe prime, the first good prime, the first balanced prime, and the first of three known Wilson primes. Five is the second Fermat prime and the third Mersenne prime exponent, as well as the third Catalan number, and the third Sophie Germain prime. Notably, 5 is equal to the sum of the ''only'' consecutive primes, 2 + 3, and is the only number that is part of more than one pair of twin primes, ( 3, 5) and (5, 7). It is also a sexy prime with the fifth prime number and first prime repunit, 11. Five is the third factorial prime, an alternating factorial, and an Eisenstein prime with no imaginary part and real part of the for ...

Power Factor (shooting Sports)
Power Factor (PF) in practical shooting competitions refers to a ranking system used to reward cartridges with more recoil. Power factor is a measure of the momentum of the bullet (scaled product of the bullet's mass and velocity), which to some degree reflect the recoil impulse from the firearm onto the shooter (see section on limitations). Power factor is used in competitions sanctioned by the International Practical Shooting Confederation (IPSC), United States Practical Shooting Association (USPSA), Bianchi Cup, Steel Challenge and International Defensive Pistol Association (IDPA). Calculation The power factor is based on the bullet's momentum as it's moving through the air by measuring the ''bullet speed'' using a chronograph and measuring a similar ''bullet mass'' on a weighing scale, thereafter calculating the ''power factor'' by the formula: : = \cdot Units The ''power factor'' can be represented using different units: *The SI-unit newton-second (kg⋅m/s, or sim ...

Magnum Research BFR
The Magnum Research BFR is a single-action revolver manufactured by Magnum Research. Modelled after the Colt Single Action Army, it is made from stainless steel and chambered for a number of very powerful pistol calibers, such as .500 S&W Magnum, as well as several calibers traditionally used in rifles, such as .30-30 WCF, .450 Marlin and .45-70 Government. The name "BFR" officially is an acronym for "Big Frame Revolver", although other meanings such as "Big Finest Revolver", "Biggest, Finest Revolver", and even "Big Fucking Revolver" have also been used. Available cartridges The BFR comes in two basic models, one with a long cylinder for larger rifle cartridges, and one with a more traditional revolver cylinder length (called "short" by Magnum Research). Some models that use identical bores, such as the .45/70 and .450 Marlin, can be made with two cylinders for the same gun. These revolvers were originally made by D-MAX in Springfield, South Dakota, until Magnum Research bough ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnum Research
Magnum Research Inc. (MRI) was an American privately held corporation based in Fridley, Minnesota which manufactured and distributed firearms. The majority owners, Jim Skildum (President and CEO) and John Risdall (Chairman, COO), had been with the company since its founding in 1979. In June 2010 Magnum Research, in financial difficulties, was sold to Kahr Arms, an American-based producer of compact pistols. Products MRI was responsible for the design and development of the Desert Eagle pistol. The design was refined and for some time the pistols were also manufactured by Israel Military Industries until 1995, when MRI shifted the manufacturing contract and license to Saco Defense in Saco, Maine. In 1998 MRI shifted manufacturing back to IMI, which later reorganized under the name Israel Weapon Industries. Since 2009 the Desert Eagle Pistol has been exclusively produced in the USA only, at MRI’s Pillager, Minnesota facility. Both Saco and IMI/IWI were strictly manufactur ...

Kinetic Energy
In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest. Formally, a kinetic energy is any term in a system's Lagrangian which includes a derivative with respect to time. In classical mechanics, the kinetic energy of a non-rotating object of mass ''m'' traveling at a speed ''v'' is \fracmv^2. In relativistic mechanics, this is a good approximation only when ''v'' is much less than the speed of light. The standard unit of kinetic energy is the joule, while the English unit of kinetic energy is the foot-pound.
