As far as the Gen 1 optic lugs (or lack of) were concerned, this was also proved to be a non-issue. I'm very active in the Walther circles and I've never seen nor heard of anyone having issues with their optic plate shearing off and it was actually torture tested and they couldn't get the screws to break.

This was never "proven". Walther spent a lot of time and energy trying to convince everyone their tests proved what worked for no other gun/optic worked for them.
It's like the tobacco companies paying doctors to do studies that show cigarettes are good for you.
Again, there is a reason they changed it on the Gen 2 and stuck us Gen 1 owners with an inferior product. People are moving back away from striker fired polymer guns now anyway so it's probably a moot point for new buyers.
