Vlim,

BRILLIANT! If only I had known before making one from scratch. There was my P-38, lying underneath the Luger pile in the drawer. The P-38 (postwar P-1) blade is almost exactly what I made from scratch, but 1/32" higher. Dovetail looks the same. As you say, it should be a drop-in. Could have saved myself hours of milling machine work.

David,

The P-38 sight blade I measured is exactly 1/16" higher than the original blade on my S/42 Luger. That's a lot. It should lower your point of impact close to where you want it. Gun Parts Corp (Numrich's) should have it, among other sources. If it's still not high enough, the blade is thick enough so that a skilled TIG welder can build it up and let you dress it down to where the point of aim is correct.

Thor,

.30 Luger is looking better to me all the time...fast, light, and accurate. Lead bullets, held to about 1100 FPS with conventional lube, should do nicely, not lead the bore, and cause zero wear. With Alox, I'm sure they can be driven at full velocity without leading. Lyman says .308" to .310" for both lead and jacketed bullets. My RCBS Load database specifies .308". Lee gives no info for bullet diameter in their .30 Luger data sheet, which is strange. My main reference for dimensions is "The Illustrated Reference of Cartridge Dimensions", which shows a bullet diameter of .3095". I guess measuring or slugging a specific bore would be the only way to know for sure.
