Will a spring kit for a K and L frame work on a M-12-2? I think I read somewhere that the frame was not exactly the same as a standard K frame until the M12-4 version. I want to tune my recent purchase and am not sure if a spring kit is the same.
There is no difference between steel K-frame and aluminum K-Frame revolvers springs. On all models from 12 through 12-3 the internal parts and the stocks are different because of the thinner frame.
