I have a S/A 1911 and I am wondering if it is common for the slide to make contact with outside of the barrel hood when fired. I have contact marks where the locking lugs on the slide ride across the barrel hood. The gun has never failed to function but the marks are unslightly.
+1. Common. I have sometimes tried to smooth rough edges of lug cavities in the slide by wrapping 600 grit sandpaper around a wooden dowel and lightly polishing upper inside area of slide. Am not really sure that it helped to any significant degree.
