These Fluted barrels have cosmetic issues on the fluted part, made by the manufacturer.
They are fully functional and will provide the same results as a perfect barrel.

Pistol shooting is a top level sport
Major advantage gives a precision match barrel, which differs from the original barrel by best fitting, special profils 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 life time 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
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 polygon (60°) with slightly rounded edges. For this reason IGB barrels are having a longer life time 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/viscouse and flexible are not exempting each other, but are combined in IGB Austrias 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, mady by IGB Austria get treated the modern way of Hardening - the Plasmanitration. Diamond hard smooth surfacees without the known weaknesses of the tenifer process (loss of material flakes on the inner surface). Plasmanitration delivers characteristically a very dark grey sufrace, is corrosion resistent and comes close to diamond hardness.
IGB Austria works with special in-house adapted machinery to insure 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 to shooters needs.
