XM17 Modular Handgun System Competition
The XM17 Modular Handgun System (MHS) competition was a United States Army and United States Air Force competition for a new service pistol. The Modular Handgun System was solicited by a Request for Proposals in September 2015 and is anticipated to be the next U.S. military standard side arm replacing the Beretta M9 pistol and the SIG Sauer M11. The U.S. Marine Corps also participated in the program to have input on source selection, but likely will not order the resulting weapon until their current pistols' life-cycles end in the mid-2020s. The competition was first announced in 2011, but multiple delays pushed the solicitation deadline to February 2016. SIG Sauer's entry was declared the winner on January 19, 2017, with plans to begin fielding before the end of that year. The XM17 and XM18 versions of the SIG Sauer P320 were chosen for the full size and compact pistol versions. After acceptance into service, the handguns got the designations M17 and M18, respectively.

Terminal Ballistics
Terminal ballistics (also known as wound ballistics) is a sub-field of ballistics concerned with the behavior and effects of a projectile when it hits and transfers its energy to a target. Bullet design (as well as the velocity of impact) largely determine the effectiveness of penetration. General The concept of terminal ballistics can be applied to any projectile striking a target. Much of the topic specifically regards the effects of small arms fire striking live targets, and a projectile's ability to incapacitate or eliminate a target. Common factors include bullet weight, composition, velocity, and shape. Firearm projectiles Classes of bullets There are three basic classes of bullets: * Those designed to maximize accuracy at varying ranges, * Those designed to maximize damage to a target (by penetrating as deeply as possible), * Those designed to avoid over-penetration of a target. This is done by deformation (to control the depth to which the bullet penetrates) which, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Picatinny Rail
The Picatinny rail ( or ), or Pic rail for short, also known as a MIL-STD-1913 rail, 1913 rail or STANAG 2324 rail (cancelled), is a military standard rail interface system that provides a mounting platform for firearm accessories. It was originally used for mounting of scopes atop the receivers of larger caliber rifles. Once established, its use expanded to also attaching other accessories, such as: iron sights, tactical lights, laser aiming modules, night vision devices, reflex sights, holographic sights, foregrips, bipods, slings and bayonets. An updated version of the rail is adopted as a NATO standard as the STANAG 4694 NATO Accessory Rail. Significance Because of their many uses, Picatinny rails and accessories have replaced iron sights in the design of many firearms and available as aftermarket add-on parts for most actions that do not have them integrated, and they are also on the undersides of semi-automatic pistol frames and grips. When adding a Picat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magazine (firearms)
A magazine is an ammunition storage and feeding device for a repeating firearm, either integral within the gun (internal/fixed magazine) or externally attached (detachable magazine). The magazine functions by holding several cartridges within itself and sequentially pushing each one into a position where it may be readily loaded into the barrel chamber by the firearm's moving action. The detachable magazine is sometimes colloquially referred to as a " clip", although this is technically inaccurate since a clip is actually an accessory device used to help load ammunition into a magazine. Magazines come in many shapes and sizes, from tubular magazines on lever-action and pump-action firearms that may tandemly hold several rounds, to detachable box and drum magazines for automatic rifles and light machine guns that may hold more than one hundred rounds. Various jurisdictions ban what they define as "high-capacity magazines". Nomenclature With the increased use of semi-au ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pistol Grip
On a firearm or other tools, a pistol grip is a distinctly protruded handle underneath the main mechanism, to be held by the user's hand at a more vertical (and thus more ergonomic) angle, similar to the how one would hold a conventional pistol. In firearms, the pistol grip is located behind the trigger and generally held by the hand that operates the trigger. Rifles and shotguns without pistol grips are generally referred to as having "straight" or "upland" (shotguns only) style stocks. Some firearms, starting from a 1840s Belgian carbine,https://littlegun.be/arme%20belge/artisans%20identifies%20l/a%20lesoinne%20et%20pirlot%20gb.htm and most automatic weapons in the 20th century (e. g., Chauchat MG, Thompson submachine gun, AK-47 assault rifle), have a second frontal pistol grip (or foregrip) on the firearm's fore-end to be used by the support hand for better stability in operation. Pistol grips can also serve multiple functions, such as a magazine housing (in semi-autom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suppressor
A silencer, also known as a sound suppressor, suppressor, or sound moderator, is a muzzle device that reduces the acoustic intensity Sound intensity, also known as acoustic intensity, is defined as the power carried by sound waves per unit area in a direction perpendicular to that area. The SI unit of intensity, which includes sound intensity, is the watt per square meter (W/m2 ... of the muzzle report (sound of a gunshot) and muzzle rise when a gun (firearm or air gun) is discharged, by modulating the speed and pressure of the propellant gas from the muzzle and hence suppressing the muzzle blast. Like other muzzle devices, a silencer can be a detachable accessory mounted to the muzzle, or an integral part of the gun barrel, barrel. A typical silencer is a metallic (usually stainless steel or titanium) cylinder containing internal sound baffles, with a hollow bore to allow the projectile (bullet) to exit normally. During firing, the bullet flies through the bore with litt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

United States Army Rangers
United States Army Rangers, according to the US Army's definition, are personnel, past or present, in any unit that has the official designation "Ranger". The term is commonly used to include graduates of the US Army Ranger School, even if they never served in a "Ranger" unit. The vast majority of Ranger school graduates never serve in Ranger units and are considered "Ranger qualified". In a broader and less formal sense, the term "ranger" has been used, officially and unofficially, in North America since the 17th century, to describe light infantry in small, independent units—usually companies. The first units to be officially designated Rangers were companies recruited in the colonies of New England by the colonial militia to fight in King Philip's War (1676). Following that time, the term became more common in official usage, during the French and Indian Wars of the 18th century. The US military has had "Ranger" companies since the American Revolution. British units late ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
