Narrow market as it refers to a specific personal security weapon. This is the kind of name that if you made a site and optimized it for the se's for "tasers" you could make some nice money as you probably won't have too much competetion say compared to optimizing a site for "security"or "weapons" or "self defense". And you have the benefit that your sites name is the word you can optimize for - its easy to remember for the customer imo.
