What is a key factor in properly maintaining a firearm?

Regular cleaning after each use is essential for properly maintaining a firearm because it helps to remove residue from firing, such as gunpowder, lead, and other contaminants. This residue can accumulate and lead to corrosion, malfunctions, and decreased accuracy if not addressed. By cleaning the firearm, you not only ensure its reliability and functionality but also extend its lifespan.

While using high-quality ammunition, storing the firearm securely, and carrying it at all times may have their own importance in firearm safety and performance, they do not compare to the foundational need for cleanliness. Without regular maintenance through cleaning, even the best ammunition or storage practices won't prevent a firearm from becoming unreliable or unsafe to use. Therefore, regular cleaning after each use stands out as a critical factor in firearm maintenance.
