The purpose of this Firearms Safety and Handling Manual is that if you come into contact with a firearm, for whatever reason, whether it be because of the nature of your work or occupation, for sport, for fun, or simply out of curiosity, you will know how it works, as well as the essential safety measures for its handling, to prevent accidents caused by lack of knowledge in its manipulation. It aims to raise awareness of the importance and respect that should be given to one of humanity's greatest inventions. This manual will address the subject concerning the basic knowledge that a person who handles a short modern firearm should have; this guide does not aim to provide an extensive treatise on the origin, history, classifications, or types of ammunition of firearms in general. Instead, it offers essential information to help you handle a short firearm with care whenever the need arises. Therefore, I will leave aside the subject of long guns, but only after pointing out that the same safety rules described in this manual also apply to long guns.
