While there are different kinds of firearms, most share a basic anatomy. In pistols, the cylinder is replaced by the chamber which holds one cartridge at a time in firing position, just like the cylinder in the revolver.

10. Semi-Automatic “Off Safe”
Here, the safety has been turned OFF, revealing the RED (or ready) dot indicating that the gun is “HOT” and ready to fire

11. Semi-Automatic with Slide Open
To begin to shoot a semi-automatic, the slide must be pulled back to load the first cartridge into the chamber.
After the first shot, subsequent cartridges are automatically “chambered” or loaded.

12. Semi-Automatic with Loaded Magazine
The magazine which holds the cartridges (see the one visible at the top of the magazine) must be inserted into the pistol’s grip. A typical magazine may hold 7 to 10 cartridges. Some can hold more.

13. Semi-Auto with Cartridge in Chamber
Even when the magazine is removed, there may still be a cartridge in the chamber. This has led to many unintentional shootings even among those who are well-trained.
