If you are new to Semi Automatic Gun, before you buy give a look to our buying guide. Hope this will be helpful in choosing the most powerful semi auto handgun.

What is a semi automatic gun or Pistol?

What is a semi automatic gun or Pistol?

A semi-automatic pistol is a gun in which the shooter pulls the trigger, fires one bullet, and new ammunition is loaded automatically. The trigger is pulled, a single round is fired, and the mechanism reloads the next round. Only one round is fired per pull of the trigger.

A semi-automatic pistol uses some energy generated when fired to eject a spent cartridge case and load a new one. The advantage of semi-automatic pistols is that magazines can hold more rounds. They also typically have a lighter trigger pull, can fire multiple rounds quickly, and are thinner and more compact.

With higher ammunition capacities, faster reloads, and better ergonomics, semi-automatics generally make it better self and home-defense handguns. There are also more calibers to choose from and a more excellent range of accessories and custom parts.

A semi-auto pistol uses the energy of a preceding round being fired to operate a mechanism that automatically loads a new round into the chamber but does not fire that round. It can accurately be called an “autoloader.” A massive advantage of semi-automatic pistols over revolvers is the magazine capacity. A typical gun holds six rounds in a cylinder.

The magazine of a semi-automatic pistol usually holds 7 to 15 rounds. Reloading a semi-automatic pistol is generally more accessible because you can empty an empty magazine and insert a loaded one.

Effectively you can fire as fast as you can pull the trigger; however, that is usually the absolute worst accurate way to shoot.

Pros & Cons Of Semi Automatic Pistol

Let’s discuss the pros & cons of semi-automatic pistols.

Advantages

  • Higher magazine capacity.
  • Ability to quickly load a new magazine.
  • Lighter, more slimmer, and easier to conceal.
  • Magazines can hold more ammo.
  • Can fire ammo in quick succession.
  • “Typically” have less recoil.
  • Easy to reload.

Disadvantages

  • Reliability isn’t its finest quality. Greater chance of failing.
  • Less stopping power.
  • More complicated to use.
  • Overall more expensive as compared to similarly well-made revolvers.
  • Another problem that can occur is jamming. If a semi-auto gets jammed and you don’t know how to unjam it quickly.
  • Because of the progressive nature of a semi-auto, another con of purchasing one is affordability.

How A Semi-Automatic Handgun Works?

Semi-Automatic Handgun Works Image Credit: https://www.britannica. com

A semi-automatic pistol is a type of pistol that uses a single chamber and barrel. The pistol fires a round, ejects and ejects an empty cartridge case, and then loads a new round into the chamber each time the trigger is pulled.

There are eight actions that occur as a pistol fires a projectile:

  • Feeding – moves the cartridge from the magazine to the barrel.
  • Chamber - the cartridge is fully inserted into the chamber of the barrel.
  • Locking - the barrel and bolt are mechanically "locked".
  • Shooting - the drummer hits the primer of the cartridge, gunpowder ignites, pressure builds up, and the projectile (bullet) leaves the barrel.
  • Unlocking - the bolt and barrel are mechanically separated slightly.
  • Extraction - the bolt moves back and the "hook" of the extractor pulls the empty cartridge case out of the barrel over the edge.
  • Ejecting – The ejector hits the empty cartridge rim, turning it/pushing it out the slide ejection port.
  • Cocking – The trigger and the firing pin are set together and ready to fire another round.

Types of Semi-Automatic Pistols

There are several ways to distinguish semi-automatic pistols other than make, model, and caliber. One by type of Action, which includes:

  • Single Action Only (SAO): A single-action (SA) semi-automatic pistol must be cocked by first depressing the Action or bolt. If a round is already chambered, manually cocking the hammer. The M 1911 pistol is the most famous example of the SA semi-automatic pistol by Browning. When you draw a weapon from a holster, you turn off the safety by raising it to eye level.
  • Double Action: Most double-action semi-automatics are built to be DA/SA, which is Double-Action to Single-Action. This type of pistol action gained prominence in the 1970s and 80s with miracle nines—i.e., 9mm pistols with high-capacity magazines—such as the Smith & Wesson Model 59. , SIG Sauer P220 & CZ 75, Beretta 92 . Most instances have a combined safety and deactivation lever.

Some people believe that a single-action pistol or handgun has better triggers than double-action pistols. This is because single-action triggers do not have to overcome the additional cocking resistance of double-action pistols.

Types of Semi-Automatic Pistol Mechanisms

There are generally three semi-automatic pistols: blowback, recoil, and Gas-operated.

Blowback-Operated Actions

In blowback semi-automatic pistols, the bolt is not mechanically locked, and the weight of the heavy bolt and a powerful recoil spring keep the bolt closed. When fired, the pressure in the chamber created by the cartridge ignition pushes the bolt backward, compressing the return spring. The inertia of the bolt, assisted by the resistance of the spring, keeps the bolt closed long enough for the chamber and bore pressure to drop to a safe level.

Recoil-Operated Actions

In semi-automatic recoil pistols, the barrel is blocked by the action when the action is closed. When fired, the barrel and bolt bounce back some distance before the barrel unlocks, allowing the bolt to move further back to complete the cycle. Most self-loading pistols chambered in 9mm and above use a recoil mechanism. There are many mechanical designs for locking and unlocking such pistols' breeches.

Gas-Operated Actions

In gas locks, propellant gas under high pressure is removed from the bore through a small hole in the barrel. This, in turn, puts pressure on the piston or other component, pushing it back to unlock the bolt and actuate the bolt.

Difference Between Semi-Automatic Pistol Vs Revolver

Semi-Automatic Pistol

  • Semi Automatic pistols are magazine-fed pistols that use the energy of a fired cartridge to retrieve and eject a fired cartridge, re-cock the hammer, and feed a new cartridge into the chamber.
  • Semi Automatic pistols are fast because they automatically reload.
  • It can be a good option for home defense because of the recoil energy that cycles the action.
  • They are much easier to handle than heavy guns like revolvers.
  • The magazine of a semi automatic pistol will hold between 7 and 15 rounds.
  • Semi Automatic pistols are more complicated to clean as compared to revolvers.
  • Reloading is generally easier with semi automatic handguns.
  • Quickly loading a new magazine is one of the best advantages of semi automatic pistols over revolvers.

Revolvers

  • The revolver gets its name from the rotating cylinder into which the cartridges are loaded. The firing mechanism rotates the cylinder before each shot, indexing the next cartridge before the trigger.
  • A revolver will hold six rounds in its cylinder.
  • There are no magazines necessary to operate the revolver.
  • Revolvers are also easier to maintain & clean.
  • The revolvers simplicity and their parts robustness allow them to shoot larger calibers.
  • Revolvers are more reliable & they will shoot more rounds without mechanical issues affecting their operation.
  • Revolvers are easier to handle with their slightly higher weight.
