It is also stressed in the instructors workshop, the we stress this when teaching new Glock armorers.
That being said, IF, as you mentioned, the lead is hard enough (somewhere upwards of 30 on the brinell scale) you could get by, providing your barrel isn't shot out. But me? I only run FMJ's in my Glocks.
