Homemade Pistol To Carbine Conversion

Readers of 'Expedient Homemade Firearms' Volume I and II may find the following 9mm Machine Pistol design of interest.

The firearm is constructed using similar materials and techniques as those illustrated in my previous books. The following construction drawings will be familiar to readers already conversant with my previous designs. The pistol uses the same design magazine shown in Volume I, though I have included the magazine base plate spring design, shown in Volume II, as a design improvement.

I have designed the bolt to be a simple unit easily machined using a lathe, rather than assembling the bolt from the selection of hardware products shown in Volume I and II.

In short, I have designed the machine pistol with the slightly more advanced home-gunsmith in mind and to enable relatively simple home workshop construction.
