Customer Questions

How effective is a 45 ACP suppressor at reducing sound compared to other calibers?

A .45 ACP suppressor is quite effective due to the subsonic nature of most .45 ACP ammo. Suppressor enthusiasts have always enjoyed 45 ACP for its great sound performance.

What should you consider when buying a suppressor for a 9mm pistol?

Key Considerations for a 9mm suppressor: Sound Suppression: Opt for models with proven decibel reduction. Size and Weight: Ensure it doesn't unbalance your pistol. Mounting Compatibility: Ability to work on multiple firearms, including pistons and carbines.(common 9mm thread pitch is 1/2x28).

How does a modular 9mm suppressor perform compared to traditional models?

Modular 9mm suppressors offer the ability to adjust length and performance. In the longer configuration, they provide maximum sound suppression similar to traditional full-size suppressors. In the shorter setup, they are more compact but with slightly reduced noise reduction. This flexibility allows users to tailor the suppressor to their specific needs, making modular suppressors more versatile than fixed-length models.

What are the key differences between a 9mm suppressor and a 9mm silencer, if any?

The terms "suppressor" and "silencer" are used interchangeably and refer to the same device. Both are designed to reduce the sound of a firearm's discharge.

Can a 9mm pistol with a silencer be used for concealed carry, and what should you know about compatibility?

There are 9mm silencers for concealed carry, such as the JK Armament CCX 9. It is incredibly compact and very light, hardly noticible. The CCX 9 does not require a booster, making it ideal for EDC.

What are the benefits of using a short 9mm suppressor versus a standard-size model?

Benefits of a short 9mm suppressor include: Improved Maneuverability: Easier handling, especially in confined spaces. Reduced Weight: Less front-end weight can enhance firearm balance. Compactness: More suitable for holstering or storage.

How effective is the Obsidian 9mm suppressor compared to other modular suppressors?

The Rugged Obsidian 9 is highly regarded for its modularity, allowing users to switch between a full-length (7.8 inches) and a short configuration (4.8 inches). In its full-length setup, it offers superior sound suppression, while the short mode provides a more compact option with slightly reduced noise reduction. Compared to other modular suppressors, the Obsidian 9 stands out for its durability, ease of disassembly, and excellent performance in both configurations.

What is the quietest 9mm suppressor available on the market today?

The Rugged Obsidian 9 and CAT Street Crack are often cited for their exceptional sound suppression in the 9mm category. Both suppressors utilize advanced baffle designs and ample internal volume to maximize sound suppression.

How quiet is a 9mm suppressor, and what factors influence noise reduction?

A suppressed 9mm pistol can reduce the sound level to hearing safe levels. Factors influencing noise reduction include: Ammunition Type: Subsonic ammo is quieter because it eliminates the sonic crack. Suppressor Design: Baffle structure and internal volume can affect performance. Barrel Length: Longer barrels can slightly reduce noise.

What is the smallest 9mm suppressor, and is it effective for noise reduction?

The SilencerCo Spectre 9 is an incredibly compact mm suppressor. Despite its compact size, the Spectre offer effective noise reduction suitable for most shooting applications.

How does a 9mm silencer improve shooting accuracy and noise reduction?

A 9mm silencer reduces muzzle blast and recoil, which can improve shooting accuracy by minimizing muzzle rize and reducing kick. Noise reduction is achieved by trapping and slowing the escaping gases from the gunshot, significantly lowering the sound signature. This not only makes shooting more comfortable but can also reduce shooter fatigue and flinching, further enhancing accuracy.

What is the best 9mm suppressor, and how does it compare to other suppressors on the market?

The Dead Air Wolfman, SilencerCo Omega 9K, and Rugged Obsidian 9 are among the top-rated 9mm suppressors on the market. Silencer Shop carrys many amazing slencer all suited for different tasks.

What is the best 45 ACP suppressor for pistols, and how does it perform?

The "best" .45 ACP suppressor often depends on individual preferences, but popular choices include the Rugged Obsidian 45 and the Dead Air Ghost-M. These suppressors are renowned for their sound reduction, durability, and compatibility with various pistols. They significantly lower the noise level when shooting, enhancing shooting comfort without compromising firearm performance.

What should I know about installing a 45 ACP suppressor on a threaded barrel?

Ensure that the barrel's thread pitch matches the suppressor (Usually .578x28 for .45 ACP). Clean both the barrel threads and suppressor mount before installation to prevent debris interference. Hand-tighten the suppressor securely. Regularly check that the suppressor remains tight during use.

What is the optimal barrel thread pitch for a 45 ACP pistol when using a suppressor?

The optimal barrel thread pitch for most .45 ACP pistols is .578x28. This is the industry standard, ensuring compatibility with the majority of .45 ACP suppressors available. Always verify the thread pitch of both the barrel and suppressor before installation.

Is all 45 ACP ammo subsonic, and what is the difference between subsonic and supersonic ammo?

Most standard .45 ACP ammo is subsonic, traveling below the speed of sound (~1,100 fps). Subsonic ammo avoids creating a sonic boom, resulting in quieter shots when suppressed. Supersonic ammo exceeds the speed of sound, producing a sonic crack that suppressors cannot eliminate. Using subsonic ammo maximizes the effectiveness of a suppressor.

What are the key differences between a 45 ACP silencer and a 9mm suppressor?

The primary differences are the bore size and internal volume. A .45 ACP silencer has a larger bore to accommodate the bigger bullet diameter and usually more internal volume to handle the increased gas from the .45 ACP cartridge. A 9mm suppressor has a smaller bore and is optimized for the pressures and gases of the 9mm round, offering better suppression for that specific caliber.

What is the thread pitch of an FNX 45, and why is it important for suppressor use?

The FNX-45 Tactical typically has a barrel thread pitch of .578x28. Matching the suppressor's thread pitch with the barrel's threading is crucial for safe and secure attachment.

How does the RAD 45 suppressor perform on a 45 ACP pistol?

The RAD 45 suppressor is known for its modular design and effective sound suppression. When used on a .45 ACP pistol, it significantly reduces noise and recoil. Its modularity allows users to adjust the length and weight of the suppressor to balance sound suppression with maneuverability.

Can I use a 45 ACP suppressor on a Glock 45, and what should I consider?

Despite its name, the Glock 45 is a 9mm pistol. While a .45 ACP suppressor can be used for 9mm pistols, you can get better performance from a dedicated 9mm silencer. For 45 Caliber Glocks, like the Glock 41, 45 cal silencers like the Rugged Obsidian 45 are excellent.

What is the thread pitch for a 45 ACP suppressor, and how does it affect compatibility?

The common thread pitch for .45 ACP pistols is .578x28. This thread pitch must match between the barrel and the suppressor to ensure proper attachment. Using the correct thread pitch ensures a secure fit and safe operation of the suppressor.

What are the benefits of using an FNX 45 Tactical with a silencer?

The FNX-45 Tactical is designed with suppressor use in mind, featuring a threaded barrel and suppressor height sights. Using a silencer with this pistol reduces muzzle blast and noise, enhances shooting comfort, and minimizes recoil. The raised sights allow for better aiming over the suppressor, maintaining accuracy.

Is 45 ACP ammo subsonic by default, and why is this important for suppressor use?

Yes, 45 ACP ammo is inherently subsonic due to the mass of the bullet. This means it will sound excellent when suppressed, as there is no supersonic crack. Suppressed 45 ACP is incredibly quiet and will help to significantly protect your hearing.

How does a 45 caliber suppressor compare to a 9mm suppressor in terms of performance?

Both 45 caliber and 9mm suppressors can be incredibly effective and reduce gun shot sounds down to hearing safe levels. 45 ACP is naturally subsonic, which will sound better in a suppressor than supersonic 9mm rounds.
