That was not my pic. That pic was one of those hot "fully supported barrel only" 10mm loads shot out of an older 10mm barrel if memory serves me right.
Even the 1911 guys run into support issues trying to make major with .38super. The ramped 1911 barrel is about as close as I have seen to full support.
It is not that the older Glock barrels were oversized. They just were generous in the amount of chamfer at and around the top of the feed ramp to help ensure reliable feeding. Some guns have worse support than even the older Glocks.
