HK P2000
The Heckler & Koch P2000 is a German semi-automatic pistol introduced late in 2001 and intended primarily for law enforcement, paramilitary, and commercial markets. It is based on the USP Compact pistol. The P2000 was designed specifically with improved ergonomic characteristics; it has features that reduce handling related stresses, while at the same time increasing user handling and comfort. Design details From the success of the USP series, came the P2000. Originally designed for the German Customs organization, it was basically a requirement for an updated, more ergonomic version of the USP Compact, contoured for carry, adding a customizable grip and replacing the proprietary mounting rail with the one specific to a light they requested. Beyond securing this contract, it was the P2000, along with a number of the later introduced P2000SK as well as USP Compact LEM, that won the DHS/ICE contract discussed previously; a massive contract for the company. For that contract and for U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
40 S&W
The .40 S&W is a rimless pistol cartridge developed jointly by American firearms manufacturers Smith & Wesson and 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 (9mm size) semi-automatic handguns. It uses diameter 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 ease of reloading during a gunfight. The FBI was satisfied with the perfor ...

Laser
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word "laser" is an acronym for "light amplification by stimulated emission of radiation". The first laser was built in 1960 by Theodore H. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow. A laser differs from other sources of light in that it emits light which is ''coherent''. Spatial coherence allows a laser to be focused to a tight spot, enabling applications such as laser cutting and lithography. Spatial coherence also allows a laser beam to stay narrow over great distances (collimation), enabling applications such as laser pointers and lidar (light detection and ranging). Lasers can also have high temporal coherence, which allows them to emit light with a very narrow spectrum. Alternatively, temporal coherence can be used to produce ultrashort pulses of ligh ...

Heckler & Koch Pistols
A heckler is a person who harasses and tries to disconcert others with questions, challenges, or gibes. Hecklers are often known to shout encouraging comments at a performance or event, or to interrupt set-piece speeches, with the intent of disturbing performers and/or participants. Origin Although the word ''heckler'', which originated from the textile trade, was first attested in the mid-15th century, the sense "person who harasses" was from 1885. To ''heckle'' was to tease or comb out flax or hemp fibres. The additional meaning, to interrupt speakers with awkward or embarrassing questions, was added in Scotland, and specifically perhaps in early 19th century Dundee, a famously radical town where the hecklers who combed the flax had established a reputation as the most radical and belligerent element in the workforce. In the heckling factory, one heckler would read out the day's news while the others worked, to the accompaniment of interruptions and furious debate. Heckling ...

4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. In mathematics Four is the smallest composite number, its proper divisors being and . Four is the sum and product of two with itself: 2 + 2 = 4 = 2 x 2, the only number b such that a + a = b = a x a, which also makes four the smallest squared prime number p^. In Knuth's up-arrow notation, , and so forth, for any number of up arrows. By consequence, four is the only square one more than a prime number, specifically three. The sum of the first four prime numbers two + three + five + seven is the only sum of four consecutive prime numbers that yields an odd prime number, seventeen, which is the fourth super-prime. Four lies between the first proper pair of twin primes, three and five, which are the first two Fermat primes, like seventeen, which is the third. On the other h ...
