Best backup or self defense pepper spray?
That’s a hard answer to give because there are many variables in deploying pepper sprays but the best for the price that is easy to use and lasts a long time is the Kimber Pepper Blaster. This design is much better than the previous guardian angel which felt more like a TV remove than a firearm. I personally have demonstrated several of these for students and everyone thought they were very easy to use and a better option than bottle pepper sprays. Everyone still comes in here to pick up the same old bottle pepper sprays and although these work well on sober attackers, overly aggressive men, they are not the fastest deploy. Sure, if you train hard you can probable become more proficient but not everyone is going to have the time to do so.
There is a holster you can use with the Kimber Pepper Blaster but putting it in your pocket or a designated area of a purse is just fine. It’s not like the Kimber Pepper Blaster is going to jam up on you from pocket lint. There are no mechanical parts to move other than the trigger. You get almost a 4yr lifetime out of these pepper blasters and they are very easy to toss in a your pants pocket. The Tru Spec tactical pants and Woolrich Elite pants all have pockets that you can use that will fit these quite nicely. I highly recommend these for gifts or for backups for personal protection.
