Black oxide provides minimal protection against corrosion, unless also treated with a water-displacing oil to reduce wetting and galvanic action. In colloquial use, thin coatings of black oxide are often termed "gun bluing", while heavier coatings are termed "black oxide". Both refer to the same chemical process for providing true gun bluing.

Black oxide or blackening is a conversion coating for ferrous materials, stainless steel, copper and copper based alloys, zinc, powdered metals, and silver solder. [1]
The gun uses a smooth single-action striker-fired trigger mechanism. [2] The frame is made out of polymer, [6] the slide and barrel are made out of 416 stainless steel [7] and the magazine is made out of black oxide alloy steel. [8] PSA offers the barrel finished in several colors, it can be bought threaded and non-threaded. [9]
True gun bluing is an electrochemical conversion coating resulting from an oxidizing chemical reaction with iron on the surface selectively forming magnetite (Fe 3 O 4), the black oxide of iron, which occupies the same volume as metallic iron.
Gunpowder is a low explosive: it does not detonate, but rather deflagrates (burns quickly). This is an advantage in a propellant device, where one does not desire a shock that would shatter the gun and potentially harm the operator; however, it is a drawback when an explosion is desired.
Nitrous Oxide . Also known as “laughing gas,” nitrous oxide is commonly used in dental procedures because it is very safe and leaves your system quickly—no downtime needed. Despite its ...
