I don't know - I did have a Glock blow up in my hand and we never did figure out how to blame that one on limp wristing. Eventually, we decided that the problem was caused by thinking about limp wristing on the previous shot, which caused the slide to fail to return completely to battery, which eventually caused the next round to be unsupported by the chamber.
The great thing about Glocks is that when they do blow up in your hand, not only don't you notice it much because the gun vents the explosion downward, but also you just have to return the gun to Tupperware for replacement of the module parts that you've destroyed.
