We now offer custom PVD finish options.  Walther barrels are now available in our standard black finish as well as silver and copper PVD coatings. PVD (Physical Vapor Deposition) coatings are an extremely hard coating that offer aesthetically pleasing colors and increased lubricity.  Our CrN PVD coating is a silver finish similar to that of stainless steel.  Our TiCN PVD coating is a satin copper.  For colors, please see images at the top of the page.  PLEASE NOTE THAT PVD FINISHES ADD APPROXIMATELY 2-3 WEEKS TO LEAD TIME.


Our standard black coating is a black oxide finish.  It is a deep black finish similar to that of DLC, but will wear much quicker.  The DLC coating is an extremely hard, thin film finish that is very wear resistant.  The longevity of our barrels are not affected by the coating selected.  We manufacture these barrels from 4140 gun barrel quality steel due to this steels superior ability to handle heat when compared to other steels that are used for gun barrels.

The life of the barrel will not be affected by the coating selected.  Only the external wear of the finish will vary.  All PVD and DLC finishes will be similar in their resistance to wear.
