Thanks for the info ! The contrast isn't as great when you see the real pistol but it is noticeable.dsk said:Nice-looking piece. It's interesting that after parkerizing the slide came out much darker than the frame. Colt was having similar problems with their WW2 replicas for awhile as well. The reason is that Colt's slides are hardened while the frames are not, and hardened parts usually show up darker after parkerizing. If you look at original WW2 Colts you'll usually see where the front of the slide is darker than the rear half, because back then only the front of the slide was hardened.
