Since we're way off the topic anyway... I must pose the devil's advocate question.
Why do people (not ya'll) get so worried about Glocks? Revolvers operate the same exact way (pull trigger go bang no safety mechanisms beyond the trigger pull) and I've been shooting, holstering, and stowing them places for... well... over half my life now (such as it is).
My 686, 629, GP100, etc have absolutely zero safeties of any sort beyond the trigger guard. No nervousness on my part, no accidents. At least the Glock has the Rube Goldberg trigger.
As much as I have come to like the elegant grip safety of the XD design (Was skeptical at first) and agree it's inherently mechanically safer, I don't really think the Glock pistol is any more or less safe than its owner.
