I really appreciate the feedback on my question. I have visually checked out the holes on my 12 and 20 ga S57Es and the 20 (the one with the centering lever) has a bit of ovaling evident but not much in my opinion. The pins do not appear to have any wear at all to the naked eye. So, I took them to the range and thoroughly enjoyed some five stand and skeet. While I didn't shoot as well as I used to when I shot more often, I am sure it wasn't the guns' fault! I shot a 20 at low gun skeet and a 19 at five stand...but as I haven't shot for a few months...oh, well....). I, for one, do love the overall beauty of a shotgun and the S57Es were hand engraved - I think are very nice looking guns and handle great for me and are still somewhat affordable, too. Well, thank you all again for the info!
