The Westerner Series from Olympic Arms (who's 1911 line was formerly known as Safari Arms, Inc, when M.S. Safari was purchased back in 1989) and shown in the previous pictures is a highly sought after line of 1911 that are in perpetual demand and therefore, perpetual back-order status.
The process used to create the case-colored look is in fact an old-school arsenic/calcium based process used to harden steel with the much desired case-cloring actually being a bi-product of the process. In the Old West, when metallic cartridge engineering was out-pacing the engineering of carbon steels, this process was introduced to add the necessary strength to the metals, and the coloring associated with the process was most often polished off. Now, it is the coloring that is desired and hardening.
Most current methods of case coloring are either simply heat relayed, or are a modified formula no longer like the original (because of the arsenic content), and require a great deal more heat than is used in the original process. Therfore comparing most commonly used methods with the original old-school methods is akin to the 'apples/oranges' argument.
This process used by Olympic is (because of the hazardous material issues) is contracted out, and is highly controlled, and while it does add significant tensile strength to the materials (in this case 4140 Chromemoly steel), it is simply not permitted to become brittle. This is controlled by factors such as chemical balance, heat and time in the bath. First produced in 2002, the Westerner Series was not officially cataloged by Olympic until 2004 as decisions were being made to handle volume, logistics, settling on models and options etc, as the first production models filtered through the system.
Let me be adamant in stating that outright dogmatic statements as we have seen here in this thread, or any suggestions or intimations that Case Color Hardening would "
ruin your slide", or that, "
it would break because it would be too hard/brittle for a part that takes abuse like that", are
patently false, are made without any scientific basis in fact. Making such statements without a full understanding of the process is moot in any regards. With a 35 year history in the firearms industry, and a ten year history of the series with 8 of those years as some of the most heavily demanded 1911's on the market, the track record thus for for Olympic Arms Westerner Series 1911's speaks for itself.
May it also be noted that Kimber produced a 100 Year Commemorative model 1911 with a Case-color hardening finish as well.
I appreciate the opportunity to respond to this issue directly to your forums. If you have any questions or comments concerning the Westerner Series, please address then to me directly, and I'll be happy to address them.
