I'd say the internals will look really good once you get everything cleaned up. I figured from the pictures that it hadn't been cleaned up real good yet. Didn't want to tell you to give it a good cleaning if you already had!
And I've never liked rubber grips on black guns to begin with, so I'd say if you slapped on some decent original wood grips, that thing would look like a completely different gun.
Now looking forward to the range report.
