I've owned a bunch of 250/320's with the polymer grip modules and they always show small scuff marks really easily. I've even bought new modules because of it. I've just recently found that the Scotch Brite ultra fine pads are perfect for cleaning those scuff marks to look like new again. I've used the Scotch Brite pads on my stainless revolvers for years so I figured they were too rough for polymer. I took a small pad and just rubbed it ever so lightly front to back, almost letting the weight of the pad do the work, and it is amazing how they clean up by doing this.

I discovered the same a few years ago with my first P320 when I stippled the grip. As you noted, the key is a very light touch. I used an aerosol (silicon or WD40) on the grip module after the 3M process. Apply, let it sit for awhile and buff off. That left a nice flat sheen.

Hmmm... I may give Scotch Brite a try. One of my 250s is getting pretty scuffed from Kydex wear.

Be aware there are different grits of the 3M pads. You want the least aggressive for this to work w/o damaging the polymer. You may only find the green in your typical home center. An automotive paint supplier should carry a variety or order online...

That for sure. I only use the Ultra Fine 7448 pads on my polymer and stainless guns.

3M 7745 gold is a solid choice as well as it falls between silver and white pads.
