Frequently Asked Questions

What makes a 9mm suppressor suitable for pistols?

9mm suppressors on pistols typically require a Nielsen device, also known as a booster or piston. This spring system allows the suppressor to move with the pistol's recoil, enabling the firearm's locked breach system to cycle correctly.

How can a 9mm suppressor be used on a rifle?

To use a 9mm suppressor on a fixed barrel rifle, you'll need a fixed barrel spacer to replace the booster's spring mechanism. This allows the suppressor to be safely mounted and used on platforms like 9mm carbines or lever-action rifles.

What is the advantage of a Tri-Lug mount for 9mm suppressors?

The Tri-Lug mounting system offers a very quick and secure way to attach and detach 9mm suppressors, especially on pistol caliber carbines like the MP5 or CZ Scorpion. It's designed for rapid deployment without the need for traditional threading.

Are all 9mm suppressors good for pistol caliber carbines (PCCs)?

While many 9mm pistol suppressors can work on PCCs, dedicated PCC cans are often designed for higher round counts and potentially lower back pressure. Some robust 9mm cans, like the YHM R9, are even rated for rifle calibers, offering versatility.
