I 'know someone' who works for an armed security company. This person was led to believe that the company did regular training courses for firearms, first aide and other things. He has came to realize this is not at all the case and the only training made available is an optional Intro to Handguns class designed for new gun owners. This person luckily works at sites that he is the only armed guard so he is not held back by others lack of training. He has recently taken a Defensive Handgun class and an Indiana gun law class. What other classes/instructors would be recommended for someone in this situation? He mostly works at an ER but occasionally works at apartment complexes. Any suggestions are appreciated. Thank you.
