Mag Catch Fell off S&W mdl.410

Hi guys my Mag catch nut fell off while at the range today and was wondering what part I need to fix it.

I have a metal magazine catch pin...
plastic magazine catch nut...
and a magazine catch spring...

It looks as if there may have been a plastic O-ring inside the magazine nut that wore out and needs to be replaced.

I cannot find an exploded parts diagram for my SW410/411 to determine what I need. Any ideas?

I got my concealed weapons permit in the mail yesterday and the mag catch broke today.. what luck.

Here are some pics to help out with the description.... FYI: The magazine is empty it is just holding the magazine catch pin in place for the photos.

Brownells has a schematic of a 410 on their web site.

Thanks for the site TJH3781. I ordered a mag catch nut.. I believe this is what was worn out. We'll see.
