It is not a tapered pin and not a tapered hole so it doesn’t matter.
I would not suggest hammering it out, you run the chance of swelling it and then you will be in for a real bad time. I used the vice method for my AMD-65 and a 40 ton press for the Polish under folder kit from Dan’s. The vice worked fine for me and I only used the press because I was going to a friends shop. If the pin will not move at first leave it in the vice for a while and then retighten it, keep this up you can also hit the vice with a B.F.Hammer but you will mar your vice. Make sure that your pin bolt or what ever you are using to drive out the pin is as straight as possible.
I used a 4” two arm gear puller from harbor freight to remove the barrel from the AMD 65 it came out smooth. I bushed it up with nickels to avoid marring the barrel. I saw this on someone’s web site, and liked the idea.
