Self-loader is a term that refers to a type of handgun that automatically loads a new round after the previous round has been fired. While the term self-loader is commonly used, there are several other synonyms that can be used to describe this firearm. These include semi-automatic, autoloading, and self-loading. Each of these terms indicates the same basic functionality of self-loading, but with slightly different nuances. Semi-automatic, for example, suggests that the firearm has an automatic loading feature but also requires manual action from the shooter. Regardless of the synonym used, self-loading firearms are commonly used for personal defense and target shooting due to their ease of use and ability to rapidly fire multiple rounds.
