US gun-maker Smith & Wesson to report record profits

One of the world's most famous gun-makers, Smith & Wesson, is expected to report bumper profits on Tuesday.

In 2012 the number of Americans applying for gun ownership background checks increased by nearly 20 per cent on the previous year.

But renewed calls for stricter gun legislation in the United States could mean the gun industry's boom is short-lived.
