I apologize if this is a repetitive post, I just could not find what I was looking for. I recently purchased a M9-A1. I had several failure to ejects with the first 100 rounds I shot at the range. I talk to Steyr and Jeff sent me new extractor and pin. My question is, does anyone have specific instructions maybe with pictures on how to replace these parts? Also as I am new to the handgun world, what are the best instructions for tearing the gun down and cleaning it?
