While we are on the subject of sneaky, silent weapons, the .30/.44 Magnum rifle variant shown in Trey Knight’s hands was based upon the Ruger Super Redhawk. The .22/.38 Special GP100 variant was a handgun only.

The ammunition for the KAC suppressed revolvers used a captive sabot. The large caliber sabot stopped against the forcing cone of the small caliber barrel to seal the cylinder gap. The propellant gases were then left to flow into the suppressor. The rifle used a 145gr .30 caliber bullet, while the pistol used a 47gr .22 caliber bullet.

In articles that I’ve seen, the project was credited to C. Reed Knight, Jr. and John Anderson. However, the cartridge concept is derived from an earlier design by Charles R. (Bob) Olsen. He saw it as the basis for a high velocity revolver cartridge without the need to use a bottlenecked case with its setback problems. He called it the “Invicta.” The models he showed to the shooting press back in the early/mid-80s were built on Dan Wesson revolvers. I suspect that no one wanted to market it due to the possibility that some idiot would slip a standard cartridge into the cylinder and try to shoot it out of the smaller diameter bore.

Olsen’s US Patents can be seen online:

For those who are not aware, Bob Olsen was also involved in the development of the .41 Action Express and .50 Action Express cartridges.
