Someone is selling a Delta Elite 10mm. Gun SN is a DE117XX # so its a early blued Delta right? I think thats right anyway, I am writing for confirmation. But the slide is stainless, with the straight vertical serrations milled in the slide, not on an angle, and it is roll marked Colt Goverment Model. But it(slide) is definately stainless, and the frame is blued. Any help out there? Did the slide suffer the early stress cracks, and they replaced it w/ a stainless, killing the value of the gun I would think?? I dont know, just guessing.
