Glock 29 10mm barrels from ebay

[STK-300]

Has anyone tried a Glock 29 10mm barrels from ebay? I think the main offerings are from Spectre Supply and HGW. Are these any good? Do they feed reliably? How about chamber support?

Bumping this up. I'm curious as well.

I got lucky and picked up a kkm barrel on eBay at a great price.
