Idk, as an American Doug Ford seemed to have a lot of power when he was mayor. And now as governor premier he's overriding the Constitution (notwithstanding) or maybe I'm misunderstanding
I'm in Autodesk most of the time, but have operated (read: babysat) on occasion, our multi-axis mill.
My point is that once the full workflow is set up and documented it can be transmitted.
Maybe I'm thinking about it differently than you in terms of final output. I'm not talking about copying a Glock piece by piece. I'm thinking closer to the type of gun Tetsuya Yamagami used to assassinate Abe. Basic, simple, and repeatable if not reusable. Something so easy it could eliminate moving or flipping the workpiece all together. Silencers could also be fairly simple to automate.
Honestly, the only difference would be the jigs and clamping, and making sure the tools are in the correct loading bay/socket. Everything else can be done by a 3rd party and distributed like it is with 3d printing. even the stock can be pre selected, it's not any different than recommending abs over nylon or tpu.
I think the difference in magnitude only applies to the price of the machine.
Idk when you were in college, but tormach has come a long way with automation. It wouldn't surprise me if someone had automated paths & tool changes and was able to pump out gun parts without much human intervention.
I'll say it again for emphasis you don't want to be in the same room or building as an ozone generator. It has been linked to lung cancer
