Can someone talk about what the theory is for establishing the correct rear sight depth (NOT width)? For air pistol....
Thanks!

From what I know, rear sight depth is like most issues in shooting: There are several ways approach it.
I myself use a square proportion for my sight picture. That means that the rear sight depth is the same as my front sight width (not actually, but it looks so in the sight picture). My coach likes a very shallow rear sight. Being an old guy with not such great eyesight anymore, he claims a very shallow rear sight will make vertical alignment errors more obvious. It's another way, but I've tried it and don't feel very comfortable with it.
I've seen some people modify the rear sight blades in their air pistol to a U-shape. I've never tried this tecnique in air pistol (it's more popular in free-pistol) but I've heard it's popular with Russian shooters, and I've seen some very fine air pistol shooting being done this way.You can use a properly cut razor blade attached to your rear sight to make this modification without mutilating the original rear sight of your air pistol.
I hope I've given you something to think about and experiment with.

I also use a rear sight notch that gives me the appearance of a perfectly square front sight. The front sight I use is almost (but not quite) the width of the bull at my arn's length. We've also put many of our club pistol shooters through a sighting triangle test to help them determine how wide (or narrow) their rear sight notch should be for best accuracy. E-mail me if you
're interested in this.
On the U-shaped notch, the idea is that if the sights are misaligned, you see not only a narrower slit of light on one side, but it is shallower as well, presumably making it even easier to notice and correct.
