Bluing or blueing: A passivation process in which steel is partially protected against rust, and is named after the blue-black appearance of the resulting protective finish. 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 ...
Bluing, sometimes spelled as blueing, is a passivation process in which steel is partially protected against rust using a black oxide coating. It is named after the blue-black appearance of the resulting protective finish.
Modern industrial approaches to forming black oxide include the hot and mid-temperature processes described below. Traditional methods are described in the article on bluing. They are of interest historically, and are also useful for hobbyists to form black oxide safely with little equipment and without toxic chemicals.
The Official Police was machined of fine carbon steel, with blued or nickel-plated finishes, and was offered in 4, 5 and 6 inches (100, 130 and 150 mm) barrels.Built on Colt's .41 or "E" frame, it was manufactured in a variety of chamberings, including .22 LR, .32-20 (discontinued in 1942), .41 Long Colt (discontinued in 1938), and the most common and popular, the .38 Special.

Glock Ges.m.b.H., an Austrian firearms manufacturer, uses a black Parkerizing process as a topcoat to a Tenifer process to protect the slides of the pistols they manufacture. After applying the Tenifer process, a black Parkerized finish is applied and the slide is protected even if the Parkerized finish were to wear off.
It was initially released with a 6" barrel, then a 4" barrel, and finally a 2.5" barrel which was the shortest barrel that could accommodate the vent on the rib. The Python was the first time Colt used the Royal Blue finish, coming from a very high polish on the gun and then bluing.
Front cover – The M16A1 Rifle – Operation and Preventive Maintenance by Will Eisner, issued to American soldiers in the Vietnam War. An inadequately maintained firearm will often accumulate excessive fouling and dirt within the barrel and receiver, which not only can clog up the rifling and decrease the firearm's accuracy and precision, but can also interfere with the proper operation of ...
