I have legoed together some P226 SAO models in different calibers other than 9mm and the slide on my 357 is a little grayer than the 40. It came off a UU frame and the 40 came from a 47 frame. I bought a 357 Legacy slide a while back to put on the slideless frame I had and it has a finish that matches the frame. I was trying to keep Elite slides on the SAO frames but the color difference is bugging me. So I'm asking what other people would do. Should I leave it alone? Swap slides with the 40? I prefer shooting the 357 over the 40. Or use a non Elite slide to get the colors to match(slide in second picture)?
