Rondrews: I have had a LOT to do with Glocks for a LOT of years including 1,120 of my co-workers using them!
Additionally I have purchased several Glocks for my own and my professional useages - in all of those years I have never heard of a comparable incident to which you allude to!
Facebook anonymous innuendo is NOT going to replace my firsthand experience with Glocks.
Glocks ARE first-rate firearms - dependability, readiness and reliable accuracy are built into them.
Re-assess your insinuation.
