Most likely then you'd leave the shop without one. Mine are worth more than $200 a piece and since I'm a machinist by trade, I cannot find anything I couldn't fix, machine, or replace.me

I assume a good gunsmith could do the same.

Those of us who aren't machinists would do better with a pistol we can buy parts for. Even a machinist might rather do machining that makes him some money.
