What should be done to the locking block after cleaning?

After cleaning, applying a light coat of CLP (Cleaner, Lubricant, Protectant) or LSA (Lubricant, Small Arms) to the locking block is essential for several reasons.

The locking block is a critical component of the M9 service pistol that helps to secure the slide to the frame during firing. Proper lubrication prevents wear and tear, enhances functionality, and ensures smooth operation. Applying a light coat allows for adequate protection against corrosion and reduces friction during the cycling of the pistol. This maintenance helps in keeping the firearm in optimal condition, ensuring reliability and longevity.

While leaving the locking block wet with cleaning solvent might seem like it could provide temporary moisture protection, it can actually lead to issues such as attracting dirt and debris, which could impede the locking mechanism's function over time. Ensuring the component is completely dry might leave it unprotected, risking rust and wear due to lack of lubrication. On the other hand, stating that no maintenance is needed contradicts basic firearm care principles, as regular maintenance is crucial for performance and safety.

Therefore, applying a light coat of CLP/LSA to the locking block after cleaning is the most effective way to maintain its proper function and prolong the life of the firearm.
