Because gold and silver finishes make the gun more "Scary".... yea... I would not be suprised if that was the case... The parts should be the name number but the model number is what makes them have to retest the guns. I think on the DE model numbers the last letter is changed or something stupid like that...Other than that I have no idea....
Mark XIX, 6-Inch Barrel, Black Oxide
Mark VII, 6-Inch Barrel
I can say there fuuun guns to fire... Expensive ammo... but fuuun, the recoil is not as bad as I feared it would be but the muzzle flash is awesome, and the sound it makes this deep deep thud type sound. But what suprised me was it was jamming like crazy! I sure as hell am not going to spend that much on a handgun to have it jam! even if its one or two times....
