We all know there are people that are living in States where carrying a firearm is not allowed, but considering how good modern technology has become, pepper sprays and tasers have become viable options for self defense. We also highly recommend people consider carrying some level of less-lethal device other than a knife or a firearm because there are are more than likely more incidences where dealing with an obnoxious bully or drunk can be diffused with pepper spray than waiving a firearm and then having to deal with law enforcement in a he said she said. While it is true that many Law Enforcement Officials have been using tasers, even those have proven to not always work.
With all of the crazy drugs people are on and how many zombie type things people take, you do have to consider that fact that less lethal weapons may not be the best option and carrying a firearm is a better thing. One of our favorite options to suggest to people are the Kimber Pepper Blaster II devices because they are shaped like a firearm and can also be holstered like one. I suggest carrying something like this as well as a firearm because it gives you some range and more accuracy than a stream spray and not the mess that a fog spray can make. There is always the chance of blow back but the liabilities are less from a legal point.
