This video compares shooting a Thompson Machine ISIS-2 suppressor wet versus dry on a CZ P-07 Duty 9mm pistol. Adding a small amount of water (approx. 5cc) to the monocore suppressor resulted in a slightly quieter sound signature. The effectiveness of the 'wet' method is highly dependent on the specific suppressor's design and construction.

Quick Summary
