Hello everybody. I picked up a S-40 a year or so ago but just recently found this site. The gun is in the 21000 range of serial numbers and is in near perfect condition in the original box with 3 mags total. Is there anything specific I should watch out for or should know about as far as malfunctions? I was reading up on the rod possibly breaking the tabs inside but i wasn't able to find any tabs in mine for the rod to break. Am I missing something? Thanks for the help. This looks like it will be a great site.
