Greetings!
I recently bought both an M&P .22 and M&P 9mm (full-size) Love both guns so far. I'm a lefty, so the fully ambidextrous features are a real plus.
I just removed the rear sight for replacement on the 9mm, and I lost the small disk underneath. (part circled in green in attached picture)
Anyone know where I can get a part number for it - or can I just describe it to S&W and get a replacement? Thanks for any assistance!
