Sverre, your question is difficult to answer until you identify the pistol and grip type.
If you are talking about your black widow, the grips are unmarked on the inside and could be a bit loose, because of the material shrinkage. If your black bakelite grips are original, each should contain a threaded hole on the inside that fits the threads of the grip screw. CAUTION: if you insert a screw in the threaded holes, they may chip the grips, so be really careful!!!
Most wood grips are marked with the last two digits of the serial number pressed into the wood. Some also have an inspection mark or waffenamt stamp. And some aren't marked at all.
Hope this helps!!
