Congrats on the 5" 29-5. The 29-6 has a slightly shorter rear sight unit and the screw is larger, going into one of the scope mounting holes instead of the small one that S&W have always had. Classic, Classic DX & Magna Classic 29-5 rear sights (& 629-3 are a one model thing and you may not be able to replace if lost.
