I took my concealed carry (SDA) class with John Hudson of Defcon Defence. I can't say enough good things about how he presented the class. He was very thorough and presented the information in a manner so that anyone can understand. His firearm instruction was also top notch. He can easily turn a first time shooter, who is maybe a little hesitant, into a confident marksman. If you are already an experienced shooter I guarantee you will still come out of the class learning something that will benefit you. I highly encourage anyone who is on the fence about getting their concealed carry license to pull the trigger and take it with John.
