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

Image Credit: https://www.britannica. comA 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:
There are several ways to distinguish semi-automatic pistols other than make, model, and caliber. One by type of Action, which includes:
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.
There are generally three semi-automatic pistols: blowback, recoil, and Gas-operated.
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.
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.
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.
