I just mounted a green fiber optic front sight on my model 97 in 44 spec. Wow, I can see again. It made a positive difference. I was told by the sales rep at Freedom Arms that I should get the green color since males tend to pick up green better than the red. She was correct. I have other red fiber optic sights but I seem to pick up the green faster & clearer. I guess I'll need to convert my model 83 also. Good shooting
