I wasn't sure if this was the correct forum for a question like this, so if its wrong please let me know. I just picked up an HK VP9 and wanted to change out the grips, but it asks for a 2.8mm punch to remove the pin. I'm still relatively new to firearms so I don't have many of the necessary tools yet. Is there something else I could use to safely (and without damage) remove the pin? Thanks for any advice.
