I have a 3-die set and I've never had an issue.
Of course, I shoot an XD.
As an engineer, I would be very interested to see how many times you can reload glocked brass and what the failure modes would be (like case head separation). I have a sneaking supicion that this, more than any other single factor, causes a stinging sensation while shooting the final round through a Glock 40. And that "fixes" like Bulge Buster will just make a bad thing worse.
