Some things cannot be mass produced the way you describe. Otherwise we would see that on the market. Why don't we see Python quality firearms currently produced? Because the guns were labor intensive and would cost too much to make.
There is a market for them, but they would cost too much to produce to be profitable. You don't know what you're talking about.
All guns have handfitted parts. Stop twisting my words around. You know very well that I am correct. You are just being a troll.
