Met my friend at the range today. He wanted to shoot his new glock 23. It was his first firearms purchase. He has shot firearms before but never owned his own. I set up him target and started to load my mags. He wasn't done yet so I shot 17 rounds. His turn, he walks up and racks back the slide, pulls the trigger and .... nothing. He says something is wrong. I walk up tap rack pull BAM. I hand it back over. He pulls the trigger and nothing. He hands it over to me tap rack pull BAM. He pulls the trigger nothing. He hands it over I drop the mag.... filled with 9mm.
