Is my Luger jammed?

Seeking clarification on this point:

Is this actually the case, that having the safety-on prevents the toggle from being worked?
Because I have noticed this on my Luger: sometimes, I can't pull the toggle all the way when safety is on, other times it is not a problem. Is this a sign of mis-assembly, or is this by design?

I ask because I can't see any mechanism or reason that would prevent the toggle from raising when the safety is on, but that's the way it behaves.
