+1L Haney said:It could possibly be blued. Just not polished before hand. If you blast a gun, then hot blue it, the results would be very much like that. Hot salts blueing is also an oxidizing process. So you have to start with a very high polish to achieve that deep, slick colour/texture. Blasting before blueing just results in a matte finish that has no rust resistant properties. It will hold oil better that high gloss. And it won't reflect light.
