1. Understand the risk
First, and most critical, is understanding the risk. Stun guns deliver debilitating shocks and cause pain. If you cannot see yourself doing this even in self-defense, consider alternatives like a personal safety app or self-defense weapons or courses.
Any weapon can also be used against you if you’re not prepared to use it. Regularly practice deploying your stun gun so that you’re ready when you need to.
2. Understand how your stun gun works
Some have switches, others have buttons, and some have both. There are dozens of designs available. Some look like brass knuckles, others are also flashlights, and some are traditional hand-held designs.
The end of the many stun guns deliver a charge when pressed against someone, completing the circuit between the short electrodes. Before contact, many of these stun guns also create a bright electrical charge and crackling sound that can serve as a deterrent to would-be attackers.
Some stun guns, like many made by TASER, fire barbed electrodes connected to the gun by wires. The barbs stick to clothing or skin so the charge can be delivered from a distance of 15–20 feet.
Most stun guns will work through light clothing, but keep in mind that heavy or bulky clothing or jackets will reduce their effectiveness.
3. Consider your habits
In your research, take into account your individual habits and situation. If you frequently travel by air, you won’t be able to take a stun gun with you on the plane. Do you rarely carry a bag? A smaller design that fits in a pocket may better serve you than a bulky one.
