cm: please reread the narrative I posted earlier in this thread. it will answer some of your questions regarding the difference between factory case hardening and after market re case hardening. a low heat, chemical process is not case hardening. it is case coloring, in an effort to simulate factory receiver case colors. unlike recase hardening, the low heat, chemical process does not disturb the original factory receiver metallurgy, and hence poses no danger to the gun or shooter...
and please note, i do no gunsmithing work of any kind. i have little specific knowledge of case hardening or case coloring. tony treadwell's book is the best description of the recase hardening process that i am aware of...my approach to all of this is as a hobby gun dealer. if enhancement increases the value of a gun and makes it more sellable at a higher price...great! if not, then don't do it.
