While we are revisiting Glock K/B's I've never seen one. Doesn't mean there hasn't been one. Saw a Colt Python "come unhinged" and lose 3 out of 6 chambers, I've seen numerous pictures of S&W revolvers taken after they basically did the same thing. Anything made by man, can and will break. I still have my Python and quite a few S&W wheelguns. Oh yeah, I still have My Glock(s)
