Luger rear sight problem(?)

[PRD1]

I received the replacement rear toggle section (with rear sight) from the Lugerdoc: the turn-around was fast and the part was exactly as described.
Installation went without a hitch - the original part was removed and replaced with the new one - no difficulty at all was experienced in driving out the original pins or replacing them in the toggle assembly. The toggle fits and functions perfectly in the pistol.
I shot it this morning, and was very pleased! The POI, previously about a foot low at 15 yards is now about 3" high at the same distance, which accords well with my previous experience with Luger pistols. The front sight needed to be driven to the left a bit to center the group horizontally (it was already off-center the other way, so it is now closer to center than originally). The final 5 rounds went into just about 1", which is outstanding accuracy, considering the somewhat tired bore, less-than ideal sight picture and typically squashy trigger pull.
If I work-up some ambition, I may fabricate a rear sight for the original, altered Artillery toggle section, but there is no urgency...
In summary, I'm very happy with the outcome! Thanks all around for the good advice, and special thanks to the Lugerdoc!
