John M. Browning – Wizard of All Modern Firearms John Moses Browning (1855–1926) ay isang kilalang imbentor ng mga makabagong armas. Siya ang nagdisenyo ng Colt M1911 .45 caliber pistol, Browning Automatic Rifle (BAR), M2 .50 caliber machine gun, at iba pa. Marami sa kanyang disenyo ay ginagamit pa rin hanggang ngayon. Parts of Colt .45 Hammer – Strikes the firing pin to hit the primer, igniting the gunpowder which burns and propels the bullet. Slide – Houses the firing pin, extractor, and sights. Moves backward during firing to eject the spent casing and chamber a new round. Ejection Port – Releases the empty cartridge case after firing. Barrel – The main and most important part of the firearm; used to guide and propel the bullet directly toward the target. Muzzle – Tip of the barrel; this is where the muzzle blast or gunshot sound is heard. Mainspring Housing / Cap – Contains the mainspring and returns the slide to its original position; also protects the mainspring. Frame – Holds all the parts of the firearm together. Trigger Guard – Safety feature of the firearm; prevents accidental pulling of the trigger. Trigger – Mechanism that, when pulled, releases the hammer or striker to fire the bullet. Grip Safety – Safety mechanism at the back of the grip that must be pressed before the gun can be fired. Magazine – Holds the ammunition and feeds it into the chamber. Rear Sight and Front Sight – Used for aiming the firearm accurately. Slide Lock / Slide Stop – Locks the slide in place; also used to release the slide after it locks open. Magazine Release Button – Releases the magazine from the firearm. Basic Parts of Ammunition Ammunition is also known as a cartridge, which is a complete unfired unit. Bullet (Projectile) – A metallic or non-metallic object that is propelled by the burning gunpowder. Powder (Gunpowder / Propellant) – Once ignited, it creates heated gas and pressure to propel the bullet. Casing (Shell or Cartridge Case) – Holds the bullet, gunpowder, and primer together. Primer – When struck by the firing pin, it produces a flash from the ignited primer mixture, which lights the gunpowder. Ballistics Definition – The scientific study of the motion of a projectile while inside the firearm, during flight, and until it hits the target. Three Branches of Ballistics Internal Ballistics – The study of projectile motion inside the firearm, from ignition of the primer until the bullet exits the barrel. External Ballistics – The study of projectile motion in the air after leaving the barrel until it reaches the target. Terminal Ballistics – The study of the effect of the projectile when it hits the target. Types of Motion Direct Motion – Straight-line movement of the bullet over short distances. Curvilinear Motion – Curved trajectory of the bullet over long distances due to gravity and air resistance.
