"When opportunity knocks!!!"

I am far from being right at times, but the attempt is still there. One has to get beat on for whatever to keep the faith sorta speak.

you might take a look at the first equation for tangent of the angle. Is it 8.1 or 81.1?

My stuff is not completely right either, as used a component of barrel length rather than sight radius.

Thanks for the nice presentation and pictorial; lot more than I did.

regards,

Opps! I did the calculation with 8.1 but mis-typed 81.1 on the figure. 81.1 inches would make a mighty long pistol barrel! The math as shown is correct with 8.1". I have corrected the image. Thanks for catching that!

I concur with your calculation. I went back to my scribbling, and plugged in the total sight radius.......8.1 I assume, and got the 0.22222222" number as you did. You did it more easily than I did, but in the end, agreement. Guess we both are hoping to help hit the mark.

I went on the Brownell's deal and it concurred as well with the 8.1 sight radius. Now........is that the real sight radius that is in mind?...

I flubbadubbed the barrel length by using 4 inches(stupid on my part), rather than the total sight radius, so my initial numbers were out of wack. Sorry about that, but has been a long week here and then some.

First, thank you Kiwi Mark... Can you tell me what you ended up with in over all height of the front sight blade from top or sight base to top of sight?.. I'm guessing around .250" overall... And also thank you Robert, Rick, and Don.. you guys have opened my eyes some in the method behind the madness!!!!

... Well, here's the final S.O.S!!! I need a couple of samples of original P.08 front sights... in "AS NEW" condition?..... Let me know price and trade preference, I'm at your mercy!...

I need two ro three.... and will listen to all offers... Let me know Guys! Best to all, til....lat'r....GT

BTW, at this point, still looking like .225" / .250" / .300" ... still listening for suggestions though???.....
