I would happily join you...

I am a shade-tree gun hack, and I have learned many of my limitations...Using anything higher than 4140 steel is too expensive for my work...Steel like 8620 work hardens quickly, especially in thin areas...8620 will get harder than HSS drills, reamers, and end mills...I have the invoices and box of junk tooling to prove it...

4140 (also called 'Ordnance Steel') is what I use now for firearms parts; it is quite user-friendly but can still be hardened & annealed/tempered...

Production firearms are like any other commodity; they are made to the lowest possible specifications to keep cost down...

If whatever was done by the OP's smith caused it to break, then IMHO, that smith did something wrong...
