At one of the online re-sellers there are a number of K 38's listed for sale with this in the description. I understand this is made for target shooting, but don't some of the competitions need the DA function?

Seems odd to me, but then I'm not a competition shooter. I am a pretty good shot with a handgun but I've never been driven to that particular mad corner of our sport! I respect the folks that do it and understand the time and dedication required.

Just curious. Y'all have some explanations?
