Glock–US Made vs Austrian Made

There is absolutely no difference other than the country of origin markings.

Let’s immediately dispel the two most common misperceptions:

  1. 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.
  2. Glocks made in Austria DO NOT use Tenifer. Nope. Not on anything new. Not since 2010. No way, no how.

The Markings

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
  • Model
  • Caliber/Gauge
  • 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 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 fact, they use the same materials, the same machinery, the same tolerances, and the same finish.

The Finish

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 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.

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.
