Sorry to hear about your incident. How many rounds have you put through your glock thus far? This is your .45acp Glock, right?
I've got about 800 rounds in my S&W M&P, and thankfully nothing has ever happened (no FTF's or FTE's). If something like this happened though, I would probably be scared to death as well.
I hope the gun is fine, and I hope you become confident again in shooting it.
On a side note, Jerry, that comic is great.
