This image from homemadeguns.wordpress.com appears to be from a Portugese police agency. Shotgun shells are often used for the clandestine manufacture of pistol ammunition. It many countries it is much easier to obtain shotgun shells than pistol or rifle ammunition. In countries where severe restrictions on the private ownership of firearms have been imposed, shotguns are the least restricted.
In the extremely restrictive Soviet Union, shotgun cartridges were relatively available. In England, the easiest firearm license to obtain is the shotgun license, as it is in Japan.
With a source of shotgun cartridges, you have everything you need to make pistol cartridges. You have lead, from which bullets may be cast. You have shotgun powder, which makes a good pistol gunpowder. And you have shotgun primers, which can work for pistol primers.
In this case, the ingenious person who desired free market firearms, made a homemade double barrel shotgun. It is a fairly simple, yet extremely effective firearm. Improvised shotguns may be the most common homemade gun around the world. If you can obtain shotgun shells, a single or double barrelled shotgun is an obvious first choice.
But this budding Portugese Colt went much further.
Desiring a reliable, multi shot, easily concealed and portable firearm, they built their own six shot revolver and unique, homemade cartridges.
From the picture, the cartridges use shotgun primers, shotgun powder, and homemade cases and bullets.
On the lower right, you can see the salvaged shotgun primers used in the homemade pistol cartridges. The left circular tin appears to hold gunpowder.
The bullets, in the plastic bag, are of the "heeled" design, which is what early revolvers used, to simplify the construction of the cylinder. The chambers for "heeled" bullets are simple bored through, without a step to take into account the thickness of the case. Caliber appears to be approximately .38/9mm. The case seems a little longer than a .357 magnum. I suspect energy levels and velocities on the order of a .38 special.
I do not know if the barrel is rifled or not. As no sights are shown, it is likely smooth bored, but the person who put this together showed enough technical ability that they could have rifled the barrel.
The box to the left of the shotgun shells looks like a homemade reloading kit. The shotgun shells seem to be typical 70mm or 2 3/4" 12 gauge.
