The $392 (Rs.24,410) gun designed by the US gun firm Taurus has no external safety clip or sights to ensure a low profile when carried.

Advertised as "the gun you wear" on its website, it is "the world's first and only curved firearm", said its developers.

With an approved patent from the US Patent and Trademark Office for its unique concept, anyone who copies the design will need to pay the company.

Requiring no holster, the gun comes fitted with a belt clip that allows it to be tucked very discreetly into a pocket or a waistband.

To prevent accidental firing, the Curve has a key attached that can be turned to engage a security lock, and make sure it does not accidentally fire while in the pocket.
