I can’t seem to get this video to play on this platform, so I watched it on YouTube. Kinda bummed out I couldn’t see all the tooling work you put into getting the frame “1st Time Quality”.
Why is polymer 80 your go to choice for Glock lower frame?
Are there other brand Glock lower frames you recommend?
I’m finding a lot of suppliers are out of OEM Glock internals, where are you ordering your pins and springs from?
