This fine firearm was crafted by a now incarcerated young gentleman using a bit of threaded pipe, a hose nipple, a bolt and a spring.

Originally a long gun locally produced for hunters, It has been modified or ‘sawn off’ into a pistol which was used in a bank robbery. A large extension spring powers the hammer which is part of a typical simple exterior lock set up. A toy cap would typically be used to prime the nipple combined, the propellant usually being black powder taken from fireworks.
Improvised pen guns made from $3 automatic center punch tools. These reportedly can fetch up to $100 when sold on the street.
Shotguns made by a 29 year old man who was arrested while trying to sell one of the weapons at a bus station in the Central Region of Rio Grande do Sul, Brazil. Each appears to be an improvement over the traditional improvised design with the addition of a ‘trigger’ type safety / barrel lock leaver.
