If you want stats...you can take Switerland as an example along with this:

In March 1982, 25 years ago, the small town of Kennesaw – responding to a handgun ban in Morton Grove, Ill. – unanimously passed an ordinance requiring each head of household to own and maintain a gun. Since then, despite dire predictions of "Wild West" showdowns and increased violence and accidents, not a single resident has been involved in a fatal shooting – as a victim, attacker or defender.
The crime rate initially plummeted for several years after the passage of the ordinance, with the 2005 per capita crime rate actually significantly lower than it was in 1981, the year before passage of the law.
Prior to enactment of the law, Kennesaw had a population of just 5,242 but a crime rate significantly higher (4,332 per 100,000) than the national average (3,899 per 100,000). The latest statistics available – for the year 2005 – show the rate at 2,027 per 100,000. Meanwhile, the population has skyrocketed to 28,189.
