Wait a second. Aren't guns legal in the UK? I think they are. I found this answer somewhere. If guns are legal in the UK, why don't people get shot more often? I think its the lack of semi auto guns.
"As far as pistols are concerned, only air or historic weapons, ie muzzle loaders, are permitted, and they cannot be carried on the person other than in a secure container, eg from car to club range.
Rifles are under Firearms Certificate, and a certificate is not difficult to obtain if you're a shooting or hunt club member or have your own suitable land, or a right to shoot over suitable land, and don't have a serious criminal record - no violent offences, no imprisonment - or medical record of mental health problems.
Rifles have to be stored at home in an approved safe, with ammunition stored separately. Weapons have to be transported 'securely,' and cannot ordinarily be carried in a public place (there are a few exceptions in practice, such as where land being shot over is divided by a country road, and hunters have to cross.)
There are type restrictions, basically intended to prevent ownership of assault rifles, but there is no problem with any classic deer rifle or vintage military rifle such as a Lee-Enfield or Mauser.
Finally, only criminals see any need for concealed weapons here."
