Most modern firearms employ this process, but some, like the revolver, do not.
As with all semi-automatic firearms, the process of pulling the trigger fires the round and also readies the next shot to be fired. Though it may seem tedious to take each of these steps individually, single-action revolvers have a lighter trigger pull and consequently better accuracy.Īlternatively, magazine-fed handguns showcase a process remarkably similar to that of a rifle’s, only on a smaller scale. Afterwards, pulling the hammer back rotates the cylinder to ready the next shot.ĭouble-action revolvers can perform all of th ese steps with one trigger pull. After the trigger is pulled, the hammer swings the firing pin into the primer of the cartridge. First, the hammer must be cocked back to ready the shot. The process of firing a revolver includes several steps, though they all happen near-instantaneously. Glock manufactured pistols have only 34 individual parts, arguably the least amount among any modern pistol. Now needing to accomodate a magazine, the parts of a pistol went up significantly in number. Over time, these new pistols branched away from revolvers. Pistols went the same way as the rifle: magazine-fed firearms. While this step forward allowed pistols to fire multiple times before needing to be reloaded, innovation demanded more than 4, 6, or 8 shots per reload. The parts of a revolver include the cylinder, hammer, and of course, the barrel. This innovation gave rise to the revolver, and brought with it an ever increasing complexity to the parts of a pistol. Even later, the cartridge was introduced to pistols. The process was rough and extremely prone to weather and misfires, and was eventually replaced by caps filled with black powder. These early pistols operated on the same mechanism that muskets did: a piece of flint served as the “hammer” to ignite the primer. Though not as long as the rifle’s, the history of the pistol begins near the same time, with a familiar firearm: the flintlock pistol. Though bolt-action requires the fewest parts to function, the inefficiency of a rifle that needs to be cocked before each shot might not be an efficient payoff for the reliability that it provides. Automatic and semi-automatic rifles require many more steps, and unsurprisingly, many more parts. Then, the spent cartridge will be ejected from the barrel as the bolt is pulled back again. Once a cartridge is in place, pulling the trigger will cause the mainspring to propel firing pin into the primer of the cartridge, igniting it and causing a shot to be fired. The magazine holds the cartridges, which are pushed into place through the pulling back and release of the bolt. Much like the original muskets, this rifle’s stock, barrel, and bolt are the three key parts.īolt-action rifles provide the simplest modern mechanism for firing. The Remington Sportsman 78, for example, has a modest list of 37 individual parts. Bolt-action rifles showcase the most straightforward firing mechanism, and consequently require the fewest parts. Whereas muskets boasted only a dozen or so, modern rifles are often manufactured with fifty or more parts. With the advance of World War I and II, innovation of rifles improved drastically.Īs technology progressed, so too did the number of parts. However, time demanded a more efficient firing method, which antiquated the ram-rod and introduced the magazine as an invaluable part. Due to this, the ram-rod was also an important inclusion in the list of rifle parts for early muskets. These muskets were only capable of firing one cartridge at a time before needing a reload an action performed by ramming powder and a musket ball down the muzzle of the rifle. Primarily, the stock, barrel, and lock were shared across all models. Notable key rifle parts that appeared with these first firearms include the hammer, striking pin, and primer. As the pioneer of firearms, the musket left much to be desired, but laid groundwork that rifles today still employ. The musket is history’s first true rifle. Whether it be pins, bushings, rails, or springs, these pieces come together to create a whole greater than its parts. The same basic premise that rifles, pistols, and shotguns operate under has remained largely the same for nearly their entire history. That being said, they haven’t fundamentally changed much at all.
As technology advances, gun features become more and more advanced every year. Firearms have come a long way in the last 657 years.
