stallones: please note the work done was not case hardening. case hardening was already done at the parker factory. it is not necessary to undo what the factory did, in order to restore case colors.

also, if you failed read my reply to 2-piper above. please do so, as you apparently are unaware of what was accomplished here.

and, do you have an opinion as to the origins of the case colors for the gun referenced in the beginning of this thread?

keep it simple and keep it safe...
