Frequently Asked Questions
How do quick-piercing CO2 systems work, and why do they matter?
Normal CO2 launchers require you to pierce the gas cartridge as soon as you load it. The problem? The pressure slowly drains over time, leaving you with a weak or useless device when you actually need it. A quick-piercing system (found in advanced self-defense tools like the P2P PGSII and HDP 50) fixes this. It lets you store the launcher fully loaded with a fresh, sealed CO2 cartridge inside the grip. When an emergency strikes, you just give the bottom of the handle a firm tap to instantly pierce the capsule. The system primes itself in a split second, giving you full power exactly when it counts.
What is the difference between a traditional stun gun and a Taser?
People often mix these two up, but they use completely different technology and require different tactical distances. A stun gun (like the disguised mechanisms in the Streetwise Stunbrella or Hair Dryer Brush) is a close-contact weapon. You have to physically press the electric arc against an attacker to cause localized pain. A Taser (like the Axon Taser 10) is a long-range device. It shoots dart probes using compressed nitrogen up to 45 feet away. Instead of just causing pain, it triggers neuro-muscular incapacitation, temporarily overriding the attacker’s central nervous system from a safe distance.
