I own a Glock 23....I have never had an issue with knowing if it is "cocked" or "uncocked" beacuse every time I handle the weapon I remove the mag and check the pipe. I thought that was a basic rule. Seems to me it is not the issue of the gun...but rather the issue of the stupid oscar moron handling the weapon.
That would have never happened if he had followed basic fundamentals of gun safety.
Peace out
