Ha! I just went down to the 'gun room' (garage) to swab out my K-20 after a fine weekend in pursuit of the wily clay target, and guess what holds the trigger plate in?

I likely noticed before but apparently forgot...

It looks to be a Torx head screw. It has 6 points, but I can't tell if it's standard or not since the guard is in the way.

So, they know about Torx 'style' fasteners in Germany and they have made it as far up the food chain as Krieghoff.
