“Stamped steel or aluminum magazines aren’t as easy as they look.”
Speak for yourself. You can’t make any money making them, but they’d be easy. After these magazines become illegal, there will be a cottage industry producing them cheaply and well.
They’ll be easy once you have the stamp and die.
And that’s where most people are going to have a problem. If you’re going to make them out of steel, you will need to use steel for the stamp and die.
For me, this won’t be a hassle at all. For most people, who don’t have a Bridgeport or CNC mill to make the stamp and die... it’s going to be a lot more challenging.
As I said, for people who don’t have machines at their disposal, the 3D printing of magazines looks very attractive.
