For cheap ones I like the NBS kits and those guns are what I use most. At least I know what I’m getting. With that said, I’ve had no issues with any cheap kits from eBay but for my duty rated stuff I buy all OEM Glock parts which costs about 3x more than NBS. Realistically I’m not sure I’m gaining anything. Maybe one day someone will blueprint a cheap kit vs OEM and do metallurgical tests.
