The American facility employs over 400 people. Glock USA has about 25% of the production capability as the Austrian plant. The Austrian made guns come disassembled and are assembled and test fired in the US facility. The guns production capacity of US made guns were up to 10,000 per week (3 shifts running 7 days a week). To assure ability to produce without interruption, Glock USA keeps one year worth of production materials (steel, polymer manufacturing materials and so on) on hand. Those cases would be too expensive and bulky to ship from Austria. The mold machines manufacture both frames as well as the polymer Glock gun cases the pistols are received in.

The US hammer forge barrel machines also come from Austria. Even the concrete floors in the US facility are identical to the Austrian plant. All CNC machines come from Austria and have been programmed by the same people who do it in Austria. Whereas, Glock has 100% control.Īs far as process in manufacturing in the US, it is absolutely identical. They may also send parts outside to get heat treated, finish or any other coatings. Most US gun manufacturers manufacture certain components in-house but subcontract out others. This allows Glock a unique opportunity most US manufacturers do not exercise. All tooling, molds, fixtures, gauging, etc is manufactured in-house in Austria. Glock Austria keeps 100% quality control of every aspect of production.Īnother interesting note, Glock manufactures in-house every single component of the pistol down to springs and pins. There are no material procurements in the US. All materials for manufacturing the frame, slide and barrels come from Austria and shipped to the US facility. The rest of the components come from Austria. The Glock USA pistols have American made frame, slide and barrel. Absolutely nothing! There are many reasons for this.

The answer in quality difference between the two is quite simple.
