Have fun digging. In the past, there were more threads on the MechTech.
Specifically, comparing the 10mm to either the colt .45 style mechtechs... or most other glock mechtech calibers.
the 10mm didn't fare well comparatively.
Unfortunately... it's been a long time since it's been discussed, so it may be difficult to find the real old threads that walked through the issues, and where actual g20 owners who had the product were discussing the issues they had.
