Opinions to the contrary, I have shot many thousands of reloaded .40 cases through my Gen2/3 Glocks without needing a bulge buster die or with any case failures other than the eventual case mouth split.
I also only load to the mid-range as I do with all cartridges. Common sense is better than opinions. Sure, if you want to push the envelop on pressure and velocity then take every other precaution. Or, if you don't want to reload Glocked cases then it leaves that much for those of us that do.
If I wanted to hoard .40 brass I would warn people not to shoot "bulged" cases!
