Suppressor

A suppressor is a device mounted on the end of a firearm barrel, designed to reduce the noise of a gunshot. Although it is commonly referred to as "silencing" a weapon, in reality, a suppressor only reduces the sound level and changes its characteristics. Full silencing is practically impossible due to the ultrasonic boom accompanying a projectile exceeding the speed of sound (unless we use subsonic ammunition).

Suppressor – what does it actually do?

Let's start with how the sound of a gunshot is created. This is a complex phenomenon consisting of several factors:

• Rapid expansion of propellant gases leaving the barrel.
• Sonic boom generated by a projectile exceeding the speed of sound.
• Mechanical sound of the weapon's operation (e.g., bolt hitting).

The suppressor mainly affects the first factor – propellant gases. The inside of the suppressor is a labyrinth of chambers and baffles that slow down and cool the gases before they escape to the outside. As a result, the sound energy is dissipated, and the sound of the gunshot becomes less intense. Sound reduction is measured in decibels (dB). A good suppressor can reduce the noise level by 20-40 dB.

It is worth noting that the effectiveness of the suppressor depends on many factors, such as:

• Suppressor design (number and arrangement of chambers).
• Weapon caliber.
• Type of ammunition (subsonic ammunition is much quieter).
• Barrel length.

Suppressor in shooting – why is it worth it?

Although suppressors are often associated with action movies and secret operations, in reality, they have many practical applications in sports shooting and hunting:

• Improved shooting comfort: Noise reduction reduces fatigue and stress associated with prolonged stays at the shooting range.
• Hearing protection: The suppressor provides additional protection against hearing damage, especially when combined with hearing protectors.
• Noise reduction: At the shooting range, the suppressor minimizes disturbing other shooters. In the hunting ground – it reduces scaring game.
• Improved accuracy: Some suppressors, due to their design, can affect the stabilization of the barrel and reduce recoil, which translates into better accuracy.

Let's also remember the psychological aspect. Less noise means less stress and greater concentration on shooting technique. This is especially important for novice shooters who may be intimidated by a loud gunshot.

Is a suppressor legal in Poland?

Unfortunately, according to current regulations, possessing a suppressor for firearms is illegal in Poland for unauthorized persons. Suppressors are treated as essential parts of a weapon, and their possession requires a special permit, which is difficult to obtain. Exceptions are authorized entities, such as uniformed services or entities conducting business in the field of arms trade.

Suppressor vs. compensator and muzzle device – what are the differences?

The terms suppressor, compensator, and muzzle device are often used interchangeably. It is worth knowing how these accessories differ, because although mounted on the end of the barrel, they perform different functions.

• Suppressor: As we already know, its main task is to reduce the noise of the gunshot.
• Compensator: Reduces recoil and muzzle climb, improving control over the weapon and enabling faster firing of subsequent shots. It works by directing propellant gases upwards and sideways.
• Muzzle device (flash hider): Reduces the flash of the gunshot, making it difficult to detect the shooter in low-visibility conditions.

Sometimes you can find designs that combine the functions of several of these devices, e.g., a compensator with a flash hider.

How to choose a suppressor (if you had the opportunity)?

If the regulations in Poland were more liberal, choosing a suppressor would be an important decision. Here are a few aspects to consider:

• Caliber: The suppressor must be adapted to the caliber of the weapon. Using a suppressor designed for a smaller caliber can damage the weapon and even pose a threat to the shooter.
• Material: Suppressors are made of various materials, such as steel, aluminum, or titanium. Steel ones are the most durable but also the heaviest. Aluminum ones are lighter but less resistant to wear and tear. Titanium ones combine high strength and low weight but are the most expensive.
• Weight and dimensions: The lighter and more compact the suppressor, the less it affects the balance of the weapon and user comfort.
• Mounting method: Suppressors are mounted on the barrel using a thread or special adapters. Make sure the suppressor is compatible with your weapon.
• Suppression effectiveness: Check how many decibels the suppressor reduces noise by. Remember, however, that the declared reduction may vary depending on the test conditions.
