Another nice restoration that the owner can now proudly show off.
That front sight looks more like a Mauser rifle sight blade, sometimes called a "barleycorn" sight and not really a Patridge blade. It's more an inverted V.
I used a Mauser front sight on my very mismatched Vopo Luger that I had a 6" .30 barrel installed on. It's a nice sight and works very well.
