Well I got my slide back today and got it all back together and ready to rock. If the weather is decent tomorrow I will be out to run another 200 rounds thru it. However I did notice when I was putting it back together that there was a bit of peening on the frame where the guide rod is contacting the frame. The aluminum frame in this area is "turned up" the slightest bit at the edge. See the pics below.
Should this be an item for concern or will it flatten itself out as I continue to break it in? I was thinking that after another several hundred rounds that if the metal isn't flattened out that I'd break the dremel and sanding wheel out and smooth it out.
