It’s time again to point out how futile the concept of gun control really is. I’ve discussed 3D printed firearms because they’re a neat demonstration of how manufacturing technology is advancing. But guns have been around for hundreds of years so it’s safe to say that manufacturing them isn’t too difficult. The Firearm Blog has a post about a semi-automatic pistol made from sheet metal. It’s an ugly looking thing but it supposedly works and the blueprints are available [PDF] for download.
What’s nice about this design is the simplicity of manufacture. Sheet metal can for the most part be shaped with hand tools. Although I doubt that this gun is terribly accurate it doesn’t have to be if used correctly (as in used at short ranges).
Many of the great guns in history have been stamped metal and many of those designs lend themselves well to a sheet metal version especially the AK platform as evidenced by the shit shovel AK. And of course them cheap smgs of ww2 can easily be made with a few trips to the hardware store.
