"Cyro-dipping"? does that imply freezing, or dipping the sidearm in liquid nitrogen/hydrogen/or what ever very cold liquid? Wouldn't that re-arrange the molecules of the steel and components in a way to weaken and make it brittle?
Only destressing I do to my EDC weapon of choice, is stripping it bare, soaking in high quality gun lube and oils, and giving it a good old fashion gun bath. Kinda like how we all take a long hot bubble bath to destress
