Caen1944,
That raised my batting average...
I saw a post here recently that someone put a set of P9 (?) sights on a P380; apparently the dovetail cuts are the same or closely similar. His purpose was to have greater visibility of the sight picture (bigger picture). Maybe the previous owner had the night sights put on and they pulled the wrong front. I am pretty sure all other models, except .380, use the same height sets.
The tritiums will be larger than stock and I don't have any Trijicons, so I can't say what their correct height is but I don't think the front should be much more than .010 above the rear. If no one on the forum can verify the correct Trijicon front and rear heights for P380, you might discuss it with Kahr. I hope it is just a front sight swap but you should verify that rear with someone, too.
edit: Caen, I can confirm the .1715 is the same height as the front on my PM9.

Reason: Confirming
