I plan to checker the backstrap of one of my SAA clones. Instead of cold or hot salt bluing, I am considering Nitre bluing the grip frame. I know that the temperature from nitre bluing will ruin the heat treatment of the grip frame, but does that matter? They make brass grip frames, which one can only assume is probably more soft than the steel grip frame would be, and the brass grip fames last just fine.
What do you think? Is this a safe route or should I stick to a hot salt or cold blue?
