S15 Combo 1 coating options include the following:

QPQ Nitrocarburizing Surface Treatment

QPQ Nitrocarburizing is a type of surface treatment used to enhance the durability and corrosion resistance of metal parts. The process involves heating the metal in a controlled environment, where nitrogen and carbon are introduced to the surface of the metal. This forms a thin layer of a hard compound called "nitrides," which increase the surface hardness of the metal.

During the QPQ Nitrocarburizing process, the metal is immersed in a special salt bath and heated to high temperatures. The salt bath contains a mixture of chemicals that release nitrogen and carbon, which penetrate the surface of the metal. The process is carefully controlled to ensure that the nitrogen and carbon penetrate to a specific depth, creating a uniform layer of nitrides on the metal's surface.

The resulting nitride layer provides many benefits to the metal parts, including increased hardness, wear resistance, and corrosion resistance. This treatment helps to increase the lifespan and durability of metal parts, making them more reliable and long-lasting.

Any “scuffing” you see in the surface finish is completely normal, and will not affect the durability or corrosion resistance of the steel.

Silver Nickel Coating 

Nickel coatings are extremely uniform, corrosion and erosion resistant and provide excellent lubricity.

Black Nickel Coating 

Black electroless nickel plating combines the same exceptional deposit properties of traditional electroless nickel plating but with conductive, black surface finish. It combines the exceptional lubricity, deposit uniformity, hardness and corrosion resistance of electroless nickel with a fully conductive and uniform black appearance.

Mag Catch Requirement

It is required to swap out your plastic OEM mag catch with either our standard steel mag catch or our premium steel mag catch.  If you don't swap your mag catch you may have reliability issues. If you use another manufacturer's mag catch you may have reliability issues. S15 magazines were designed to work with Shield Arms steel mag catches. If you have a first generation aluminum mag catch, it is required to upgrade to one of our steel mag catch offerings.


Like all Shield Arms products, our S15 magazine comes with our 100% lifetime warranty against manufacturing defects. Additionally, we also offer a Spring for Life Guarantee - wear out your spring, get a new one for free, for life.


If you live in a state that restricts magazine capacity we cannot ship to you unless you are law enforcement or otherwise exempt. If you are exempt from your state's ban please send us a copy of your documentation or official email to Please include your order number.

If you purchase from a ban state and you are NOT exempt, we will cancel your order and charge you a 5% cancellation fee.

This combo pack contains items that are controlled for export by the International Traffic in Arms Regulations (ITAR). Please check your state and local laws regarding magazine capacity restrictions.
