Fully supported chamber?

Hello All,
I have some confusion as to what a "fully supported chamber" is. I have a couple Sig pistols and a Glock pistol. I have a Glock 20 chambered, of course, in 10mm. I have heard a lot of things said about Glock barrels not being "fully supported". I want to use some "Buffalo Bore" type ammo, but have read I need an aftermarket barrel that is "fully supported". From what I understand, Sig barrels are "fully supported". The only difference I see comparing the barrels themselves is, the lock up on the hood of the barrel is symmetrical on my Sig barrels, and on the Glock barrel it is asymmetrical. It looks to me, that feature on Glock pistols is for ejection purposes. Is the difference in the barrel lug? Having different lock up types, that comparison is worthless to me. I just don't know the difference or how to identify the differences. I've searched a bit out there and also in here, came up with nothing helpful. Any guidance will be truly appreciated!
