Thank you! This Sandblast blue finish, what is it? Is it just standard blueing that, instead of getting polished, gets sandblasted for a matte appeearance? If that's the case, is it possible that instead of being refinished in blue, it was simply polished to give it that nice traditional blue look? See, the gun is highly engraved,does that tell you anything, like maybe it was engraved into the sandblast finish, and then polished up afterwards to give it a nice luster? I am not an expert on finishes, just trying to learn more about my beautiful "new" gun. By the way, there's no reason that this gun couldn't be fired with standard .38 special loads, is there? I mean, how old does a gun have to be before you start worrying about metal brittleness, like in antique (pre 1899) guns?
