I think I heard the term before Glocks were ever invented, but the action itself is not limited to Glocks. I have personally known of only one Glock kaboom, and it was not really a kaboom anything; it was a bulged barrel in a .40 Glock apparently due to a barrel obstruction. I believed then and still do that it was due to the shooter loading a 9mm into the magazine and having it feed up and into the barrel. The shooter stated that a round failed to feed and that he racked the slide again. IMHO, the 9mm fed and chambered then went far enough down the barrel to be out of sight so that the shooter thought he had a failure to feed.
