DIY break barrel shotgun pistol project
“Another nice project based on the plans of Professor Parabellum. In the short “Combat” variant and embellished with a few accessories ;)”
Sheet metal semi auto pistol seized in Brazil
A homemade .380 semi-automatic pistol more than likely based on the widely available DIY Sheet Metal Self-Loading Pistol plans. This example was seized in September in the Brazilian state of Espirito Santo.
Extremely simple, ultra compact clandestine submachine gun
A 9mm submachine gun designed to be ultra compact and use the least number of parts possible. Nearly all components are made from square tubing including a one piece push trigger which is operated with the user’s thumb.
Two homebuilt revolvers
Here are photos sent in of a pair of homemade revolvers built from the Professor Parabellum DIY .22 Revolver plans.
The version below is chambered in .22lr. A flip down side loading gate was added to the design as an improvement.
Main components shown before final fit & finish:
.22lr cylinder (left) and percussion cylinder (right).
The second gun is a ‘cap & ball’ version of the first which is chambered in .25. It was built as an exercise in demonstrating that a viable firearm can be produced without relying on any firearm components. Staying with the makeshift theme, plastic toy caps are used in place of regular percussion caps in combination with homemade gunpowder. Apparently this version shot accurately despite being smoothbore.
DIY homebuilt revolver
“Friend of mine is working on this, it’s made from the Professor Parabellum .22 plans but he’s modified it to .25 percussion. Barrel is threaded for the silencer. Still not quite finished but apparently it has been fired.”
