Hi!
The SS button looks a little odd to me, actually it looks like the ones that Johnson sells. They are slightly smaller than should be and are not silver. Can you try to scratch the runic button in an inconspicuous spot and tell me what color shows where the scratch is? What is the material in the background of the runic button? Also, take a look at the bottom of the grip. It appears as if the rest of the grip may have been repainted or refinished, is that true? The reason they would do that is to cover up the gaps around the ill-fitting runic button. There was most likely a police eagle there at one time.
I look forward to your responses.
Good Luck!
Bob
