They are extremely tight and the pin is tapered so remove it by putting any and all pressure or force against the pointed end. It may still be necessary to have a 'smith remove the pin as some are extremely tight.
I tried to remove the pin on my new MkIII using a brass hammer and a nylon punch, but no go. I walked away from it quickly when I found myself looking at my framing hammer and a set of steel punches :smile:
It's either the tightest fit pin I've ever seen and/or the epoxy finish is holding it in place.
OTOH, the action has smoothed up a bit and I'm shooting it pretty well as it is.
I like the sights, it shoots to POA, the hammer doesn't bite and it has been flawlessly reliable. Maybe I'll try to remove the pin after another thousand-plus rounds.
The end of the pin is chamfered, but the pin itself is NOT tapered. Just a tight fit combined with the spring locked into the groove to retain it. Use a large brass punch to start it, befor switching to a small steel one. Drive from R to left.
