Mossberg 590 A1 sharp edges in loading port

Anyone have a 590 A1 and tried taking the sharp edges of the loading port? Mine feels like it's going to cut every time I load a shell. Not sure if you could simply use a file and round those edges. How would you refinish the raw metal?

In my experience, which most recently involved my Mossberg 500, bluing pens don’t really work very well.
 
Contact Mossberg Customer Service and ask them what they suggest to use to
re-finish/protect that area after you remove the sharp edges.

So the receiver IS aluminum? Felt like aluminum. Soft like aluminum but a magnet stuck to it......I think it was picking up the bolt or trigger group through the AL.

ALL Mossberg shotgun receivers are machined from an aluminum block, yes there are of course multiple components inside the assembled receiver that are steel that your magnet is reacting to.
 
If it's aluminum, I can just polish it and it should look/be ok. The real question though was, anybody grind one? Willing to share pics/results/method? I'm a bit reluctant grinding on a <1 year old gun having never done anything like that...but also a little excited to experiment.....hhhmmmm

Oh yea....thanks for the feedback so far. (y)
 
I wouldn't suggest 'grinding' on anything, especially an aluminum receiver on a new gun.

Wrap a short piece of 180 grit emery cloth around your finger and simply rub it back and forth over the edge you want to soften. It won't take much and you won/t need a lot of pressure. Try to maintain an angle across the edge that will remove the same amount of material on both the outside edge and the inside. That will keep the smoothed area about the same width on both and much less noticeable even after re-blueing.

Thanks for the advice.
Yea "grinding" was more general. Wide, fine file was my indented weapon of destruction but I like your method better.
 
Go slow and steady and stop to feel your progress frequently. There's no need to go any further than necessary to smooth it out.
