Extractor

This machine pistol uses a fixed, spring-less extractor. Adding an extractor to a blowback design is usually
optional, though the simplicity of this design hardly justifies leaving it out. In this case, it is simply a strip of 2mm
sheet steel bent at a right-angle and filed into a simple claw profile after which it is then attached to the bolt via
two m3 or m4 grub screws. Once confirmed functioning of the finished extractor claw is established it can be
hardened by heating until red then quenching in a solution of salt water. The extractor claw should be made fairly
undersized so as to allow a cartridge rim to easily slide into contact with it without interfering with feeding.
