Well...took a friend to the range to do a little shooting. He said he was interested in getting a new handgun and wanted to test out a Glock 19 vs. Springfield XD9 and I happen to own both. So...we go to shoot and I ask him if he has ever been to the range and if he had shot a handgun. He tells me he has a 40 Glock and that he is familiar with handguns...so I said ok. I asked him again to confirm that he knew what he was doing and then I left him in the lane to shoot. He asked where I was going and said I was going to load some mags for my rifle. When I go to the range though...I load the mags before I leave the house...mainly to save time while there. Anyways...I stood a few feet behind him just to make sure he knew what he was doing and NOPE. He yells back...hey I think the safety is on this Glock. I'm like great...why did I go to the range with this guy...so I tell him to put the gun down and that I will explain to him how to operate the gun and basically give him some safety instruction. What irritates me is that he told me he had a "40 Glock" which would only have a trigger safety just like the Glock 19. WTF? He should have just told me he never handled a handgun before...I asked him where his gun was, and he tells me that its somewhere in his boxes...who just leaves a gun in some boxes? Needless to say...last time taking this guy to the range.
