• Building a homemade pistol:
  • It requires approximately 100 hours of machining and $75 of material.
  • It can be based on a Webley revolver, and can be chambered in.22 lr rather than the.455 Webley.
  • It takes manual indexing of each chamber and uses lower pressure loads (like matchhead powder loads).
  • It requires a milling machine and lathe for the heavy work, then your basics like a drill press, belt sander, grinder, bandsaw, etc.
  • It is recommended to serialize it for one’s own records, in case of theft.
• Registering the pistol:
  • Most states do not require guns to be registered to owners.
  • The ATF recommends that you serial number it just for your own records, in case of theft, but no binding requirements.
