A buddy of mine had a negligent discharge of a Springfield XD 45 today inside his home. Luckily nobody injured and almost no property damage. He asked me to come over and help him walk through what happened and how to prevent it in the future. The ND occurred as he was checking his carry weapon to see if one was in the chamber by racking the slide. The XD45 requires the grip safety to be engaged before the slide can be racked. While he was gripping it, the gun evidently slipped and his reaction was to squeeze, putting one through his floor. My question to this forum would be, why require the grip safety to be engaged before the slide can be racked? What reason could there be to require the only physical safety on the gun to be deactivated before you can rack the slide?
EDIT: Changed all of the Accidental Discharge language to Negligent Discharge, as it should have been in the first place. Moderator please close the thread.
Also, for anybody who is wondering, no, the word "buddy" isn't a substitute for the word "I" or "me." It truly happened to a friend who's not a member of this board. He was profoundly affected by it and wanted to make sure it didn't happen again. It's certainly not the firearm's fault, but the grip safety locking the slide seemed a little unnecessary. Thanks again for all input.
