How did they do that

The way I look at it is that there maybe some metal removed from the frame as part of process to create the scroll work but I think it is obviously on sides and is in an area that does not receive a lot of stress. Meaning even if you removed 5% of the metal there, betting there is more than enough metal there to do the job for life of gun and then some. Its simply cosmetic and the structure is probably very sound. The real issue is the strength of the metal at the face and tangs as it integrates into the the stock. I would be more concerned with a bad casting then the scrollwork weakening the action. I think they knew if they had a flawed casting or would not attempt to put so much work into it. Besides I have never heard of Parker failing there if gun was reasonably cared for, but I do think its a reasonable question. Would not want an old gun blowing up in my face just because it was pretty.

The real business happens inside the barrels. The only thing I could think of removing that little amount of metal would be to overall weight of gun and maybe balance point. I think they took in this into account when they made these guns.
