Back when I was growing up and some time after that. I put the front
sight in the bottom of the rear notch. We called it taking a fine bead.
Killed lots of squirrels and cans that way. Few years ago I put a Lyman
receiver sight on my 39-A. Now have to use a scope. Best way is to try
both ways. It's what you can shoot best. I used a German Walther it had
a v notch rear and front was inverted v. Wish I could see those sights now.
It looked a model 98 but was a 22Lr.
