I remember reading that some Glock's have a fully supported chamber and some don't. I could be wrong... I do recall that my Glock 21 didn't have a fully supported chamber, but I ran my reloads moderate and didn't have any problems. Do the 9mm Glock's have an unsupported chamber? The 9mm Lugar runs a lot more pressure than the 45ACP, so if the 45 will blow up, the 9mm is a disaster waiting to happen if it does.
