Wouldn't be the first time but how so?

In a word … friction.

Functional Purposes​

Reducing Friction and Wear: Polishing smooths out surface irregularities, reducing friction and wear. This is particularly important for moving parts in machinery, where smooth surfaces help minimize energy loss and extend the lifespan of components.

Polish makes a true stone.

Unless you have experience or a very strong mechanical aptitude, I would suggest doing nothing. Your best bet is to just purchase a lock that works correctly from the start. Would you be okay with buying a new car and then have to fix it up for it to work?

The geometry of the cock swing in relation to the frizzen swing is actually quite easy to adjust to a tight fitting and plumb tumbler bearing fit of lock plate ...

I have a lock where the cock does align squarely with the frizzen. How would you recommend I go about adjusting the swing?

Well … and you would be wrong …

I have a lock where the cock does align squarely with the frizzen. How would you recommend I go about adjusting the swing?

I've had to heat and bend several cock arms to align and or raise or lower the jaw angle to better accommodate interface with the frizzen swing.
If the bearing fit of the tumbler is loose to the lock plate then bushing and reaming it to a close fit is indicated.
As to polishing internal parts fit I say "never" but rather smooth and precision fitting is key as a certain amount of surface texture is needed to hold lube more effectively which is what should be reducing both friction and wear not metal to metal "polished" contact. Think engine piston wall honing and texturing to hold oil so metal contact is separated by a film of oil or high end guns where internal parts are given a swirl pattern of texturing to retain lube.There's a ten dollar word for the process called something like demonseaming or something like that I cannot seem to find in the spell check, to spell correctly.
Polishing anything to a bright luster makes sense for a pan or other areas where fouling will adhere but no sense at all where lubrication is required.

I've heard it called "Nano-Texturing" It's explained here in tech terms.

Tuning the internal parts on a lock , is not for amature hands. I give credit to all those good lock mechanics , that try to explain what they do , to those that have little to no experience in the art , let alone the specialized tools .

I've seen things suggested here that are the bread and butter for gun smiths fixing the fixes.

I'm reminded of a quip I heard years ago from a master heavy equipment mechanic, ( They never give me time enough to fix things "right" but they always give me time enough to fix them "Again.")
Working on guns is a lot like reloading ammo, some folks ought not to be doing it.
