Springfield Armory XD-M
The Springfield Armory XD is a series of semi-automatic pistols produced by Springfield Armory, Inc., along with follow-on variants: XD-M, XD-S, and XD-E. Polymer-framed and predominantly striker-fired, the series is manufactured by HS Produkt in Karlovac, Croatia. History In 2002, Springfield Armory, Inc., negotiated licensing rights to the United States market for the polymer-frame striker-fired HS2000 pistol being manufactured in Croatia by HS Produkt. Using XD (eXtreme Duty) branding, Springfield Armory subsequently expanded the series to include ten models in three different calibers and five different cartridges, seven barrel lengths, and six finishes (black, black bi-tone, olive drab, olive drab bi-tone, flat dark earth, and flat dark earth bi-tone). The XD sub-compact was named "Pistol of the Year" by ''American Rifleman'' for 2003, followed by the XD chambered in .45 ACP being named "Handgun of the Year" by both ''American Rifleman'' and the Shooting Industry Academ ...

45 ACP
The .45 ACP (Automatic Colt Pistol), also known as .45 Auto, .45 Automatic, or 11.43×23mm is a Rim (firearms)#Rimless, rimless straight-walled handgun Cartridge (firearms), cartridge designed by John Moses Browning in 1904, for use in his prototype Colt's Manufacturing Company, 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 standard-issue military .45 ACP cartridge uses a round-nose bullet at approximately fired from a government-issue M1911A1 pistol. It operates at a relatively low maximum chamber pressure rating ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polymer
A polymer () is a chemical substance, substance or material that consists of very large molecules, or macromolecules, that are constituted by many repeat unit, repeating subunits derived from one or more species of monomers. Due to their broad spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function. Polymers, both natural and synthetic, are created via polymerization of many small molecules, known as monomers. Their consequently large molecular mass, relative to small molecule compound (chemistry), compounds, produces unique physical property, physical properties including toughness, high rubber elasticity, elasticity, viscoelasticity, and a tendency to form Amorphous solid, amorphous and crystallization of polymers, semicrystalline structures rath ...

Rob Leatham
Robert Jennings Leatham (born January 27, 1961, in Mesa, Arizona) is a professional shooter who is a 24-time USPSA National champion and 7-time International Practical Shooting Confederation (IPSC) World Champion. Biography On Leatham's twelfth birthday, he received his first gun. His family surprised him with a new Smith & Wesson Model 34 revolver on one of their trips to shoot in the desert. He continued desert shooting throughout his teenage years and became involved in other sports such as basketball. Competition shooting Leatham's first competition took place in the late 1970s at a night shoot at the Mesa Police Department range. He shot a Smith & Wesson Model 27 revolver with a 6-inch barrel loaded with 200-grain round-nose bullets that Leatham loaded himself, including a custom holster made by local leather worker, Jess Bird, who had built holsters for Leatham's father for years.

Double Action / Single Action
A trigger is a mechanism that actuates the function of a ranged weapon such as a firearm, airgun, crossbow, or speargun. The word may also be used to describe a switch that initiates the operation of other non-shooting devices such as a trap, a power tool, or a quick release. A small amount of energy applied to the trigger leads to the release of much more energy. Most triggers use a small flat or slightly curved lever (called the ''trigger blade'') depressed by the index finger, but some weapons such as the M2 Browning machine gun or the Iron Horse TOR ("thumb-operated receiver") use a push-button-like thumb-actuated trigger design, and others like the Springfield Armory M6 Scout use a squeeze-bar trigger similar to the "ticklers" on medieval European crossbows. Although the word "trigger" technically implies the entire mechanism (known as the ''trigger group''), colloquially it is usually used to refer specifically to the trigger blade. Most firearm triggers are "single ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hammer (firearms)
The hammer is a part of a firearm that is used to strike the percussion cap/ primer, or a separate firing pin, to ignite the propellant and fire the projectile. It is so called because it resembles a hammer in both form and function. The hammer itself is a metal piece that forcefully rotates about a pivot point. The term tumbler can refer to a part of the hammer or a part mechanically attached to the pivot-point of the hammer, depending on the particular firearm under discussion (see half-cock). According to one source the term tumbler is synonymous with hammer. Evolution In the development of firearms, the flintlock used flint striking steel to produce sparks and initiate firing by igniting the gunpowder used as a propellant. The flint was fixed to a swinging arm called the ''cock''. Prior to firing, the cock was held rearward under spring tension. Pulling the trigger allowed the cock to rotate forward at a speed sufficient to produce sparks when it struck the steel frizzen. ...

Iron Sights
Iron sights are a system of physical alignment markers used as a sighting device to assist the accurate aiming of ranged weapons such as firearms, airguns, crossbows, and bows, or less commonly as a primitive finder sight for optical telescopes. Iron sights, which are typically made of metal, are the earliest and simplest type of sighting device. Since iron sights neither magnify nor illuminate the target, they rely completely on the viewer's naked eye and the available light by which the target is visible. In this respect, iron sights are distinctly different from optical sight designs that employ optical manipulation or active illumination, such as telescopic sights, reflector (reflex) sights, holographic sights, and laser sights. Iron sights are typically composed of two components mounted perpendicularly above the weapon's bore axis: a 'rear sight' nearer (or 'proximal') to the shooter's eye, and a 'front sight' farther forward (or 'distal') near the muzzle.

Concealed Carry
Concealed carry, or carrying a concealed weapon (CCW), is the practice of carrying a weapon (usually a sidearm such as a handgun), either in proximity to or on one's person or in public places in a manner that hides or conceals the weapon's presence from surrounding observers. In the United States, the opposite of concealed carry is called open carry. While most law enforcement officers carry their handguns in a visible holster, some officers such as plainclothes detectives or undercover agents carry weapons in concealed holsters. In some countries and jurisdictions, civilians are legally required to obtain a concealed carry permit in order to possess and carry a firearm. In others, a CCW permit is only required if the firearm is not visible to the eye, such as carrying the weapon in one's purse, bag, trunk, etc. By country United States Concealed carry is legal in most jurisdictions of the United States. A handful of states and jurisdictions severely restrict or b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Match Grade
Match grade frequently refers to quality firearm parts and ammunition that are suitable for a competitive match. Sometimes it also refers to other devices and parts that are made with high precision in mind. Description In firearms, the term is used to refer to ammunition and gun parts that are designed and manufactured in such a way that they have a relatively narrow tolerance and high level of accuracy. No standards are defined for its qualification and as such it is more of a relative term. In addition to its use in shooting sports, match grade equipment is often employed by military and law enforcement sharpshooters. Thus, many gun manufacturers use the term "match grade" to describe their products. For instance, the Heckler & Koch Mark 23 weapons system is considered so specifically tooled for combat that it is match grade, one primary reason that the pistol and its components were selected by the United States Special Operations Command (SOCOM) for service.
