What is the primary purpose of using Cleaner, lubricant, preservative (CLP) on the M9 Pistol?

The primary purpose of using Cleaner, Lubricant, and Preservative (CLP) on the M9 Pistol is to prevent rusting. CLP is designed not only to clean the firearm but also to provide a protective layer on metal surfaces, which is crucial in safeguarding against moisture and environmental elements that can lead to corrosion. This protective quality is essential for maintaining the reliability and functionality of the firearm, ensuring that it remains in optimal condition for use.

While cleaning and lubrication contribute to overall performance, the key function of CLP in this context is its preservative properties. Moisture can lead to rust, which compromises the firearm's integrity and can cause malfunctions. Therefore, applying CLP regularly is vital to preserving the metal components, extending the life of the M9, and ensuring it operates safely and effectively when needed.
