Is there a practical way to put a dark finish on a stainless slide?

Bead blast the slide and Use the Brownells Moly coat bake on coating; it is really hard.

There is a process that salt blackens stainless. It wears like blueing.
I know David Sams does it:
I have not been pleased with the results of spray and bake over stainless and instead have my stainless guns matte hard chromed.

...it is preferable to bead blast before using spray finishes on stainless....If you can apply it with an airbrush, so much the better.........

Or black chrome. Goes on over regular matte hard chromee because it's softer (comparatively).

Brownells sells bluing salts for stainless, but a professional bluing setup is expensive and you want to find someone who does it, as suggsted by Gunsnrovers. There is also a stainless cold blue called Instablak SS-370, by Electrochemical Products, but in my opinion none of the cold blacks are rugged enough for service wear.
It is necessary to blast stainless because it forms a layer of chromiim oxide at the surface that passivates it and helps prevent corrosion. This has to be removed to get a good chemical bond to the iron in it, so blasting is not optional.
