I bought a LWD conversion barrel for my Glock 23 (.40sw) allowing it to shoot 9mm. I thought I would be a smart boy and order the regular ss/silver variety at only $109 instead of the black oxide version at $139 and just cold blue the thing. I thought wrong. I tried the Casey Birch cold blueing kit and it did absolutely nothing.
I guess there is some sort of treatment done to the barrel or perhaps the type of metal is not able to be cold blued. Obviously I dont know anything. They dont take returns on barrels and I hate the bright look, I want it to be dark, like the original.
Other than using a black sharpie, how can I get this thing black or at least darker?
