paint over hard chrome?
I have a surplus Beretta 81 that is out for hard chrome plating. The front sight is integral with the slide, so it will get hard chromed too. I'm wondering if anyone knows a way to blacken the front sight, after it's been hard chromed, in such a way that won't just immediately rub off. Any ideas?

You can grind the plating off the face of the sight, and use cold blue.
I would try a good paint, like Alumahyde, first. |

Paint ain't likely to stick to the chrome.

The negs are that it over-sprays and will rub off over time but then it can be removed when you want it gone and will not harm your gun. It is more durable than Black markers. |

Industrial hard chrome finishes are not generally shiny. They have a frosted, bead blasted surface-so paint might stick better than you think.

Thank you for the tips. I may try a Birchwood Casey Super Black touch-up pen, and live with the reality that periodic touch-ups will be needed. If that paint is clearly inferior, I'll go with a can of alumahyde or sight black and hope for more durability.

If it's not tool late, call the plater and ask them to mask off the front sight so it remains blued.
I've found that paint adheres fairly well to hard chrome, especially if it's a matte finish. If you want to file off the hard chrome on the rear of the sight and cold blue it, I recommend Brownell's Dicrophan T4. This gives a Black color, not blue. It's also possibly the most durable cold blue and wears very well. |
