Don Nygord mentioned in his notes that he used a U shpaed rear sight to achieve his best personal record.

Any one with experience using this U shaped rear sight?

I have an unused small IZH 46m rear sight, I am thinking about milling this into a U shaped rear sight.

Before I do this, any comment on this U shaped rear sight? Psychological or is it truely optically advantageous?

What is your personal experience?

The question made me realise that I was going to square up the rear sight notch on my H208 - was being the operative word!

I have not noticed that it is U-shaped for some time - to busy looking at the front sight.

I dryfire with an old pellet gun. It's a pretty ideal setup. The rear sight is more a "V" shape and the front sight is pointed, or maybe an upsidedown "V" ^

The combination results in a W sight picture. The side patches of light have a width AND a depth to guide the alignment. I must say it works quite well.
I am just too chicken to "adjust" my real sights to match.

jackh, that sight sounds interesting. Do you happen to have a picture of it?

Have anyone tried the trapezoidal sight (G in the following picture). I think it is a good idea, as both horizontal and vertical misalignment will reflect themselves in the change of the air gap.

No picture. But combine C rear and G front. Narrow the V rear a little.

Perhaps the making of the front sight a uniform diamond shape is the key.

I milled the rear sight into a U sight.

This is what I found:

It IS easier to align front and rear sights. Very intuitive.

So my shots go off 1-2 seconds earlier than before.

Just pay attention to elevation alignment, windage alignment is just intuitive.

So the bottom line is: It IS EASIER and QUICKER to align: therefore, shots go off 1-2 seconds earlier. It has not translate into higher score yet. But it just make holding alignment easier and faster.

Less of a struggle to hold alignment with U rear sight.

Not only do I agree with Don , I also agree with guest posting just above, If you like it , do it. No skilled shooter focusses any where but at top of the front sight as that is the way you achieve a level front soght with the flat top surface of the rear sight. By moving eye focus back and forth across the top of the front sight you can keep it centered in the rear notch. If you focus on the bottom of the front sight you will have trouble doing either. The U shaped rear will not affect your sight allignment so long as your focus is where it should be. Good Shooting Bill Horton

a little reading...

Hi,
From Competitive Pistol Shooting, by Dr. Laslo Anatal:
"It helps spot sight misalignment faster: incorrect placing of the foresight will result in a gap which will be unequal not only in width but in length as well"

This would tend to support the above statement of improved speed...

Great explanation why U sight works faster in alignment.

If I'm not mistaken, example H is not a legal sight for ISSF pistol shooting; it is a closed or peep sight.
