Part of our Self Defense Products Complete Guide
Stun guns and tasers are popular self defense tools, but their legal status varies significantly across the United States. Before purchasing, it's essential to understand both how these devices work and whether they're legal where you live.
Stun Guns vs. Tasers: What's the Difference?
Stun Guns
Contact weapons that require direct touch to work. When pressed against an attacker, they deliver an electrical shock that causes pain and muscle contractions.
- Range: Contact only (0 feet)
- Shots: Unlimited (until battery depletes)
- Price: $15-100
- Best for: Close-range defense, budget-conscious buyers
Tasers
Projectile devices that shoot two barbed probes connected by wires. They can incapacitate from a distance and also function as contact stun guns.
- Range: Up to 15-35 feet depending on model
- Shots: 1-2 before reloading cartridge
- Price: $300-500+
- Best for: Distance defense, serious personal protection
How They Work
Both devices work by delivering electrical pulses that interfere with the body's neuromuscular system:
- Cause involuntary muscle contractions
- Disrupt motor function temporarily
- Create pain compliance
- Effects last only during application (stun guns) or several seconds (tasers)
The effects are temporary and generally don't cause permanent injury to healthy individuals.

Understanding Stun Gun Specifications
Voltage Isn't Everything
Marketing often emphasizes voltage (millions of volts), but this is misleading. What matters for effectiveness:
- Amperage: Determines actual stopping power
- Charge delivery: How effectively the charge enters the body
- Electrode design: Spacing and penetration ability
- Battery quality: Consistent power delivery
A well-designed 50,000-volt stun gun often outperforms a poorly-made "1 million volt" model.
Features to Look For
- Rechargeable battery: More cost-effective than replaceable batteries
- Built-in flashlight: Dual-purpose and useful for visibility
- Safety switch: Prevents accidental discharge
- Wrist strap: Prevents attacker from using device against you
- Compact size: Easier to carry and conceal
Using Stun Guns Effectively
Target Areas
For maximum effectiveness, target large muscle groups:
- Upper thigh
- Upper hip/side
- Shoulder
- Torso (below the neck)
Contact Duration
- 1-2 seconds: Pain and muscle spasms
- 3-5 seconds: Disorientation, loss of balance
- 5+ seconds: Muscle incapacitation (not always necessary)
Limitations
- Thick clothing can reduce effectiveness
- Requires close proximity (stun guns)
- Single-shot nature of tasers (one chance from distance)
- Determined attackers may push through pain
