45 machine pistol and scaled it up based on Pressure, while retaining its massive and simple internals designed to handle a larger cartridge. Rather than scaling down a rifle (the usual approach) or attempting to bring a modern 9mm design upward I selected a. Therefore a radical redesign to incorporate an unnecessary but advanced mechanism was completely eliminated.Īfter looking at well over 30 successful designs ranging from the English Sten gun to the Russian PPs43 to the American AR-15 9mm clones (which can be found in both gas operated and recoil operated versions) to the Thompson gun to the Israel UZI to the Ruger 44 mag carbine, I found the best design of all.

In fact the first designs were shown to be venting too much gas, as the barrel was actually being depressed on each shot by the action of the gas. For example the KRISS system could have been incorporated into the design, but slow motion studies showed that a simple muzzle brake could reduce muzzle rise to zero. The Max-10 Katana is designed around the cartridge and to be a carbine above all, using the best available design features as well as throwing away those that are unnecessary. While the KRISS or the MP-9 are designs with innovations, they were designed as pistols first with added capabilities. One of the criticisms of this project was that I was “reinventing the wheel” rather than coming up with something new like the Swiss KRISS or the Brugger & Thomet MP-9.

While all had advantages, the blowback design is the most robust, using simple physics of its massive bolt to contain the cartridge for just enough time to allow the bullet to exit the barrel before pulling cartridge free of the chamber. Several excellent designs exist for reliable subguns, ranging from complex locking recoil designs to gas operated and buffered designs to simple blowback designs. The lower receiver acts as a container that holds the various important parts of the firing mechanism (hammer to strike the firing pin (if applicable), the Bolt bolt (to provide a temporary wedge to the end of the barrel during firing a recoil spring mechanism to slow the bolt an ejector so that the cartridge will be ejected and a fresh cartridge fed smoothly into the chamber to be fired, repeating the cycle.
