No, you won't hurt anything with just a rag and polish. It won't really help any though. But if it makes you happy.......

FWIW, magnesium/aluminum polish won't polish steel - Well, maybe Polish steel. .

It will help. I used simichrome or flitz and polish away while watching TV. Soon you will have a mirror finish. If the ramp was blued, painted or just unfinished raw steel it will smooth it up and every little bit helps.

Yes, it will polish steel.

Are the guns not working?
I wouldn't polish anything that isn't steel.

I have always polished the feedramps on any auto I have and if done properly it will help. Anyone knows that an object will slide easier on glass than on stone, so the bullet nose will move up the feed ramp with less drag if it's polished to a mirror shine.

Put two pieces of glass together, and see how they slide!
The tip of the bullet usually glances off a point on the feedramp, rather than sliding up the ramp, so while it's good to have a smooth surface, any surface will soon become covered with firing residue, and I don't know much benefit a mirror polish really is. The shape, angle, and location of the ramp is what's really important.

'Just gotta'

Do-it-yourself can cost you a bit if you try to sell the item.

If there is a mirror reflective finish on the feed ramp, and that finish didn't come from a recognised shop like pistolwrench,etc., I will pass on the purchase.

Polishing, most likely won't help, and can lower the value, so why do it?

I have a couple of 'polished' ramps. They were done with a dab of Somechrome, my pinky, and a ratty t-shirt.

I get the warm and fuzzies looking at the ramp, but they came at a price.

Please read post #8 it is common sense.
The feed ramp is not to be modified,it is machined to close tolerances and
it is not the cause of malfunctions,no benefits can be gained from changing
its dimensions and the opposite is bound to be the result of doing that.
Polishing,lapping,fine grinding and so on remove stock from the work and
unless you have a way to accurately measure what you do and you know what
you are trying to do you should not do it.If you damage the frame then you will
ruin the firearm.

Every pistol I owned clearly shows that the nose of the cartridge doesn't "slide" up the ramp. It hits one small spot pretty hard and then bounces up into the roof of the chamber, breaks over and aligns. Polishing ramp is the last thing I would think of doing if a gun doesn't want to feed. Most people remove too much metal and change the angle. I would look at the finish of the breechface and the extractor hook first. It doesn't need to be "polished bright". Just knock any "speed bumps" off if you can feel them. Most guns have perfectly good feed ramps. All that is needed is the correct angle for the cartridge to strike.

You wont remove enough to harm anything with polish and a rag. If you polish like that all week you wont remove .001". So go at it. The result will likely not change feeding at all but it will make cleaning a little easier.
I did have a NEOS that benefitted from a polish job. That was done with a china stone. A little diferent process and you could cause damage over time.
