When Dornaus & Dixon took their Combat Service Pistol prototype to Jeff Cooper for his approval, he liked it, but it needed to be rechambered from .45 to 10mm. D&D had to go back to the drawing board and design the 10mm cartridge.
There are usually a few different variations on Gunbroker at any given time, but be warned--$5K, which is what I paid for the Marksman Special-Match model, is now considered lower end with regard to price.
@@rollo_tomasi The frames are stainless steel, not alloy. The slides are carbon steel that were sometimes chromed for various reasons, but that’s uncommon. For example, the 2 pistols supplied to Michael Man for Miami Vice have chromed slides so they would show up better in night scenes.
