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

How A Semi-Automatic Handgun Works?

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.

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.
