Test Report – “Swiss Gun Magazine” – Juni 2003 …due to the lack of mass to be moved – relative to a blowback design – the long barrel combination of 9mm Luger shoots calmly. .. shooting caliber .357Sig is a little more exciting. Somewhat more kick, but not uncomfortable at all – and nowhere near the felt recoil of the Glock standard barrels in models 31 and 32. … It became a very fun shooting, and more ammunition as originally planned was expended due to the 30 round magazine.

About the Company:

Pistol shooting is a top-level sport

Major advantage gives a precision match barrel, which differs from the original barrel by best fitting, special profiles and last, but not least, by high-end steel material of high viscosity. In contrast to stainless – high-end steel with special hardening preserves the viscosity and lifetime of a barrel. No broken ramps, no cracking of cartridge housings. Lasting best results.

Standard was yesterday… Barrel Technology by IGB Austria is the TODAY.

State-of-the-Art – Barrel Technology from Austria

IGB barrel profile – hexagonal: polygonal

IGB Austria with its in-house blank production combines both of two worlds. The conventional field-groove profile is used for best control of bullets or lead bullets. If you have a closer look at the profile you find the angle between groove-to-field to be similar to a polygon (60°) with slightly rounded edges. For this reason, IGB barrels are having a longer lifetime and are more cleaning friendly than others.

Cold Forged Steel

Unsurpassed density. Hard on the surface, “soft” inside. The parameters of a barrel to be hard/viscous and flexible are not exempting each other, but are combined in IGB Austria Barrel Production. IGB Austria forces the tool through the barrel with tons of pressure. The result is a precise, mirror polished barrel with great vibration characteristic and durability.

Plasma Hardening Procedure

Barrels, made by IGB Austria get treated the modern way of Hardening – the Plasmanitration. Diamond hard smooth surfaces without the known weaknesses of the tenifer process (loss of material flakes on the inner surface). Plasmanitration delivers characteristically a very dark grey surface, is corrosion resistant and comes close to diamond hardness.

Quality Assurance

IGB Austria works with special in-house adapted machinery to ensure best quality and precision. IGB Barrel – even if they are sold as drop-in will always go to the edge of best fitting. Tolerances are kept tight and optimized for shooters needs.

Polygonal Rifling:

Polygonal or wavy rifling has more shallow channels than traditional (Lands-and-Grooves) rifling. This allows the least amount of gas to escape around the bullet leaving the barrel. It also creates a greater bearing surface which will increase velocity and accuracy. It’s extremely important when shooting through a window/doors or other hard surfaces.

Several advantages for Polygonal Rifling:

Not compromising the barrel’s thickness in the area of each groove as with traditional rifling.

Providing a better gas seal around the projectile as polygonal bores tend to have a slightly smaller bore area, which translates into more efficient use of the combustion gases trapped behind the bullet, slightly greater (consistency in) muzzle velocities and slightly increased accuracy.

Less bullet deformation, resulting in reduced drag on the bullet when traveling through the barrel which helps to increase muzzle velocity.

Reduced buildup of copper or lead within the barrel which results in easier maintenance characteristics.

Less sensitive to stress concentration induced barrel failure.

Prolonged barrel life.
