Define "...hand made...". I think there is a huge band of definition on this point of what constitutes a 'hand made' gun. Probably a huge amount of misconception as well.
Examples:
How would someone 'hand make' a barrel (without a machine)? Would anyone want a truly 'hand made' barrel?
How would one drill a hole from one side of a reciever to the other accurately without a machine? (BTW, a drillpress, whether hand turned or powered is a "machine")
The point is: where do you draw the line on what constitutes "hand made" with specific regard to how many and what machines were used to make a gun? I believe virtually all modern high quality guns are mostly machine made with more or less hand fitting and finishing.
