Good evening all. I just received a call from Shooter's World here in Tampa, FL. It seems when one of my 645's was up there for a sear spring/half cocking issue, the tech dropped my gun and broke the rear sight. I am not angry as I know these things can happen, but does anyone know where I could find a replacement rear sight for this as they want to replace it with some sort of butchered Novak sight. Any input would be as always appreciated as this was my first 645. Thanks guys.

Jim

WAY OUTA DATE HERE BUT I GOT A NEW SET OF SIGHTS FROM TRITON (SP).INSTALLED BY PHIL AT THE OLD TRIPLE A GUN. only hiccup was most of the new sights need to be stoned for the fit , according to phil .

Thank you for the help WinMag. I will see what I can get from that resource. I appreciate it.

645 fixed sights are relatively inexpensive, however finding them in stock is a little tough. S&W sells the rear sight for $7.63 and Numrich sells it for $13.40, but both are out of stock. You might want to check with the vendors listed in this thread, 3rd Gen parts - I'm afraid we're on our own Gents , I ordered some parts from Jack First Gunshop and had zero issues, just have the S&W part number handy (104520000).

Thanks SK, I just have been reading that entire thread. Very helpful.
