I took a class on pistol basics ran by the owners Michael and Sarah Viets, extremely thorough overview of all things handgun related. Very patient, covered everything, and you can tell the owners were very passionate about their craft. Most importantly, they were serious, with an emphasis on safety. You simply don't find that level of care and focus towards firearms in Las Vegas without it being some sort of odd gimmick.
The best firearms training you will find in Las Vegas, hands down.
