- Glocks with the US country of origin markings DO NOT use parts made in Austria that are assembled in the United States. No way, no how.
- Glocks made in Austria DO NOT use Tenifer. Nope. Not on anything new. Not since 2010. No way, no how.
NOTE: The two pictures, above, look different because of the lighting conditions. However, here is a picture that I stole off of the Internet. It, clearly, shows that the two finishes look the same.
I won’t go into the different barrel proof markings. Let’s focus on the markings on all firearms. Every gun manufactured by a licensed gun manufacturer that are sold in the United States (this doesn’t include homemade stuff) require the following markings, all of which must be at least .003 inches deep whether they are engraved, cast, or stamped:
- Serial Number
- Name of Manufacturer
- Country of Origin
- Name of Importer
- City and State of Importer
Glocks made in Austria will have both the Made in Austria marking and the Glock, Inc., Smyrna, GA, which is the Name of the Importer, marking on the frame/receiver. The other markings will appear in other locations on the gun.
Glocks made in the United States will have the Made in USA marking and the Glock, Inc., Smyrna, GA marking on the frame/receiver. The other markings will appear in other locations on the gun.
Glock is a manufacturer that is certified under ISO 9001. This means that the processes are the same, in each location. In fact, they use the same materials, the same machinery, the same tolerances, and the same finish, in the USA and in Austria.
First, let’s address the favored topic of Glock enthusiasts: Tenifer.
Tenifer isn’t a finish. Tenifer is a metal treatment process. Glock stopped using Tenifer in 2010 as a result of EPA concerns around the cyanide salts that are a byproduct of the Tenifer process.
Melonite, also called nitrite, is used today and has been used for all guns made since Tenifer use was stopped. Tenifer and Melonite are similar nitriding processes. Melonite results in harder metal surfaces than Tenifer. Yes, Melonite is harder than Tenifer.
Second, let’s be clear: Both Tenifer and Melonite are metal treatments, they are NOT THE FINISH. The finish is applied after the metal is treated.
If the finish (the actual black finish) is scratched, that scratch, most likely, will not penetrate through the treatment and make the metal susceptible to corrosion. In other words, just because the finish is scratched does not mean your Glock will rust.
Glock is an ISO 9001 certified company. As such, quality is pretty much guaranteed to be top notch. At the very least, it is consistent. Glock guns made either in Austria or in the US, use the same raw materials, the same machinery, the same processes, and the guns that come out of each factory meet the same standards. If you have doubts, do some research on the ISO 9001 certification and what it takes to be certified.
