Homemade Firearms

Saturday, May 30th, 2009

India has a growing problem, James Dunnigan says, with homemade firearms, or kattas:

These weapons can be made from many common forms of steel pipe, and improvised firing mechanisms (that hit the bit of sensitive explosive at the center of the rear of the cartridge, which ignites the propellant in the cartridge and fires the bullet or shotgun pellets out the smooth bore barrel).

The easiest weapon to make is basically a single shot pistol firing a .410 (10.4mm) or 20 gauge (15.6mm) shotgun shell. Accurate enough for something within 5–10 feet. Not much good for hunting. These cost $20–$50 each in most parts of the world. The next step up, which requires an experienced metal worker and some machineshop tools, is full size (or sawed off) shotgun (single or double barrel), that sells for $80–$300. These can be used for hunting. These craftsmen can also make 9mm pistols (single shot or revolvers) for $50–$600. These weapons, because they are firing a more powerful cartridge, are more dangerous to use, because they are prone to exploding, rather than firing, when the trigger is pulled.

Ironically, people out in the countryside, where there are still dangerous animals that a gun can protect a village from, have fewer firearms. That’s because there’s more money, more to steal, and more demand for weapons in the cities.

Higher-quality homemade firearms are available in other parts of the world — some not so far away:

In some parts of the world, like the metal working center of Akwa, in Nigeria, and the Pushtun tribal territories of Pakistan and Afghanistan, there are craftsmen who can reproduce just about any modern firearm. The Akwa and Pushtun tribesmen have been making metal weapons for over a thousand years, and quickly applied their skills to firearms when they first encountered Europeans using them.

The firearm is just part of the “weapon system” though:

With all these homemade weapons, the key ingredient is ammunition. The cartridges are more difficult to manufacture than the guns, since it involves chemistry, as well as metal working and fabrication. But ammo is easier to smuggle, and once you have that, there are metal working craftsmen in most parts of the world who can figure out how to build a weapon that will fire the bullets.
