All over the nation, shooters—be they police, military or civilians—are embracing the sound of silence. The first step for those who have previously not used sound suppressors is education. We need to acknowledge that the ear-damaging noise produced by a firearm is merely a byproduct of the ignition process and does not translate to power. Extra-loud cartridges are not extra-powerful. It’s a bit childish, but equating noise to power is something men have been doing for centuries. The louder the motorcycle, the more “powerful” it must be. Noise is simply noise, and the noise produced by a firearm can and will permanently damage your hearing. What does all this have to do with the application and use of suppressors by law enforcement? Education is the answer. Before any officer can appreciate a tool, they must understand the value of that tool.

During my first introduction to the KRISS Vector .45 ACP submachine gun, one of my initial impressions was that the gun would be even better with a suppressor on it. Evan McNamara, director of sales and business development at KRISS, assured me that an in-house version was in the works. Now I can report to you that a new suppressor dedicated to the KRISS family of firearms does in fact exist. I have held it in my hand and used it on the range.

Let’s back up for just a second. The parent company for KRISS is headquartered in Switzerland. KRISS USA is headquartered in Virginia Beach, Virginia. In addition to the Vector firearms, it also offers Sphinx pistols and Defiance suppressors. All the KRISS Vector firearms available for purchase in the U.S. are built in the Virginia facility.

Every Vector SMG, pistol or SBR uses the same thread pitch, allowing the Defiance suppressors to mate with all of them. Jeff Rose Photo
