I had to do that to a Ruger LCP I had, when they first came out, back in 2008. Who ever the person was running the lathe they were running their guide rods on, wasn't paying attention, and it was so rough on the finish, that I had to fix the problem myself. It was tearing up the guide rod hole, in the slide.The sharp end of the recoil spring at the end of the muzzle is shaving away at the slide. This is after 200 rounds fired. I bought a Lakeline LLC steel guiderod and spring which has a blunted end. Taking a metal file and filing down the sharp end of that recoil spring could also work.
