Okay, so I don't sound really dumb on this, I got my answer and thanks to the guy who told me Brownell's sells a blade to fit the German dovetail front sight base. It's shoot, file, repeat as needed. My problem was not knowing whether or not the Germans used a 3/8" dovetail, and they don't, or I'd have used a Williams aftermarket with a gold bead. So, to Brownell's I go.
