Adjusting dove tail foresights

[averageplinker]

Hi,
Having decided to keep my Slavia ZVP pistol for now I would like to centralise the foresight so that I don't need to aim off. But what should I use to tap the foresight with that will not mark it but is tough enough to move it a little?
Cheers Rich.

Hi

I use the brass earth pin easily removable from any mains plug.

Spookily enough that was my first inclination!
