Without seeing a picture, I'm going to guess it's the excess polymer on the metal tab that makes up the frame rail. This often wears off after shooting the pistol. If that is it, it's not a worry.
There is a chip on one of the polymer slide rails on the frame, left side by the hammer. Is this just something that happens or it cause for concern? I'm trying to upload a picture but apparently I'm an idiot and can't operate a comp-U-Tor.

As above, this is normal. She's not a virgin anymore...
I figured it was normal but I had to be sure. Thanks guys.
