The slim black casing is hard and durable with protruding metal contacts which discharge the thousands of volts when you depress the trigger.  All stun guns feature an on/of safety switch, a detachable belt clip, handy carrying strap, and a pair of protruding test probes that ignite test shots.  Stun guns generate a high-voltage, low-amperage electrical charge. In simple terms, this means that the charge has a lot of pressure behind it, but not that much intensity. When you press the stun gun against an attacker and hold the trigger, the charge passes into the attacker's body. Since it has a fairly high voltage, the charge will pass through heavy clothing and skin. But at around 3 milliamps, the charge is not intense enough to damage the attacker's body unless it is applied for extended periods of time.  EFFECTS: Stun-gun effectiveness varies depending on the particular gun model, the attacker's body size and his determination. It also depends on how long you keep the gun on the attacker. If you use the gun for half a second, a painful jolt will startle the attacker. If you zap him for one or two seconds, he should experience muscle spasms and become dazed. And if you zap him for more than three seconds, he will become unbalanced and disoriented and may lose muscle control. Determined attackers with a certain physiology may keep coming despite any shock.
