I've seen it a couple times; so far only with mismatched pistols.

Like Doubs said, check and make sure it is clean.

Sear bar spring being weak can be a cause, as can someone messing with the sear engagement to give you that light trigger pull.
Lugers just don't have nice, light trigger pulls- if they do they probably are borderline for "doubling". JMHO.
