Troubleshooting my new luger.

[HisSoldier]

This happened with the non-fluted firing pins,

Those fluted FP's first came out on the mid thirties right? I have a 1920 Commercial, haven't seen it yet, I bet it won't have the flutes. This supposedly NRA Excellent DWM has a Mec-gar mag, so I suppose the value being less (Drum roll, here it comes) would it detract significantly from the value if I made flutes in the FP per photos I've seen? I have a complete commercial machine shop, so it would be done nicely. Is the hardness such that it would have to be form ground in a surface grinder or will a carbide ball end mill cut it? From blown up photos it looks like the three grooves are about .015" deep.
Thanks.
