Suppressors, commonly referred to as silencers, are indispensable tools for reducing noise and muzzle flash in various shooting applications. A key consideration for users is whether to run a suppressor “wet” or “dry,” as each method offers distinct benefits and trade-offs tailored to different shooting scenarios.
In this blog post, we’ll explore what it means to run a suppressor wet versus dry, and how each approach impacts performance—especially when it comes to 9mm pistol-caliber carbines (PCCs).
When you run a suppressor “wet,” you’re introducing a liquid—usually water, wire-pulling gel, or even a specialized suppressor coolant—into the suppressor’s internal baffles before firing. The liquid evaporates as you shoot, helping to cool the expanding gases and reduce the sound signature. This process creates more turbulence inside the suppressor, making the gas lose energy quicker and diminishing the overall sound.
Where Wet Suppressors Shine: Running a suppressor wet can be especially beneficial for close-quarters environments where additional noise reduction is critical, such as indoor ranges or tactical scenarios. For 9mm PCC users, this method offers maximum decibel reduction for those who prioritize noise reduction above all else.

Drawbacks of Running a Suppressor Wet:
Running a suppressor “dry” refers to using it without any added liquid. This is the standard method for most civilian and professional applications.
When Dry Suppressors are Ideal: Running a suppressor dry is generally the best choice for extended shooting sessions, like range days or training sessions, where consistency across shots is key. For 9mm PCC shooters who prefer low maintenance and convenience, dry suppressors deliver consistent performance without the hassle of reapplying liquid.

Drawbacks of Running a Suppressor Dry:
While many suppressor-compatible firearms can handle either wet or dry suppressors, specific setups like 9mm pistol-caliber carbines (PCCs) may perform better with one method depending on the desired outcome. Running a suppressor wet on a 9mm PCC can maximize sound suppression, which is especially beneficial for indoor shooting, tactical scenarios, or when maximum noise reduction is a priority. This approach can make a noticeable difference in lowering decibels for those seeking a quieter firing experience.
On the other hand, for extended range sessions or training, running the suppressor dry might be the better choice. Since 9mm PCCs produce less heat than larger-caliber rifles, a dry suppressor can manage the heat adequately while allowing for consistent performance without needing to reapply liquid. Additionally, the convenience of a lighter, lower-maintenance setup may appeal to shooters who prioritize ease of use over the absolute quiet of a wet suppressor.
How Much Quieter is a Wet Suppressor?
Wet suppressors can reduce the sound of a gunshot by an additional 3 to 10 decibels compared to dry suppressors. This difference is highlighted in our testing of the Vanquish 9mm suppressor, which demonstrates the effectiveness of wet suppression on sound reduction.

Impact on Accuracy and Performance
Wet suppressors don’t typically impact the firearm’s accuracy for the first few shots. However, as the liquid evaporates, minor inconsistencies may arise if the liquid isn’t reapplied. In contrast, dry suppressors provide consistent accuracy over long shooting sessions since there’s no variable of evaporating liquid.
In extreme cold, liquid in wet suppressors can freeze or thicken, reducing its effectiveness in which using a specialized suppressor coolant may help maintain performance. In hot or arid climates, the liquid in a wet suppressor may evaporate faster, meaning it needs more frequent reapplication. Dry suppressors are typically more consistent across a range of environmental conditions, making them the preferred choice for extreme or varied climates.
The decision to run your suppressor wet or dry largely depends on the specific circumstances of your activity. Here’s a quick breakdown of when to consider each method:

Dry Suppressor:
Both wet and dry suppressor setups have unique advantages tailored to different scenarios. A wet suppressor offers increased sound suppression and heat reduction but requires more maintenance and regular reapplication of liquid. A dry suppressor, on the other hand, provides low maintenance, consistent performance, and suitability for longer shooting sessions.
How you run your suppressor depends on your needs, shooting style, and desired sound suppression.
