This does not bother me at all.
This is like complaining the car owner, or the corner gas station guy, can't overhaul a 2008 Mercedes-Benz engine.
I am a shooter, not a gunsmith, nor do I wish to be a gunsmith.
Krieghoff "annuals" are recommended about every 25,000 to 50,000 firings. I've had many annuals done where the firing pins still appeared new.
Only one time I had cratered firing pins and truly needed them replaced. That was in 1977, I believe, on a well used 32 I had bought second hand.
It is all about reliability. No one yet exceeds Krieghoff reliability.....
Everybody wants to play the game "king of the mountain".
