Ryan, 
 
Don't be thrown off by the discussion of twist or Damascus barrels.  Your gun has steel barrels.  Better pictures of the barrels may give a better clue as to whether the barrels were hot blued or rust blued.  I think it is difficult to tell by your photos.  If they were rust blued then there should be no worry about that aspect.
