With the exception of GIs that took war souvenirs to the local bumper shop, firearms were not chromed- they were (and are) nickel plated. There is a reason for the distinction- thickness and adherence to the base metal. I have some nickeled guns, some stainless, some blued, some parkerized, etc. For discreet carry, I prefer blued- it does not jump out at you visually. Reflection off a nickeled weapon interfering with sight picture COULD be an issue some day, never has been for me. Nickel was introduced as a means of resisting rust. Stainless has largely replaced it from a functional standpoint.
