World's smallest gun triggers fears

What you're looking at is the world's smallest revolver. It may look like a toy, but stick a few miniature bullets into the .7 inch barrel and it becomes a fully functional firearm.

At two inches (5.5 cm) long and weighing under an ounce (0.7 oz), the SwissMiniGun C1ST is a highly sought after collectors item. Making the parts and assembling the gun requires the skill of a master craftsman, all of which are trained at jewelry and Swiss watchmaking. Thus about only 100 are handmade each year, with each order customized to the client's specifications, including the option for a special model made of 18k gold. Adding the double-action .09 caliber six-shooter to your collection will run you at least $6,705.

However, the fact that a firearm this tiny actually works makes gun regulators quite nervous. For instance, the bullets are so minis cue that firing a cartridge essentially smashes the bullet, making them impossible to trace to the original model. And being that it fits in the palm of your hand or inside your shoe, it's also highly concealable. U.S. gun laws prohibit firearms that can slip by undetected at airports and require that working guns come with a barrel that's at least 3 inches long. Needless to say, the C1ST has been banned in the US and the UK.
