The Meprolight Tru-Dot Adjustable Night Sights for S&W K, L and N frames (Meprolight part no. 227703101) pair a fixed tritium front with a windage and elevation adjustable rear. Meprolight lists this part number for K/L/N frames with the FS ramp insert, in the non-DX style or dovetail. Green Swiss tritium sits in both sights, so there is no battery or charging, and the sights are always on. The rear sight adjusts for windage and elevation, which lets you compensate for bullet weight and distance when zeroing, while the front sight is fixed. The sights are designed as replacement parts for the standard sights and mount directly with minor modifications.
