Is there a formula that takes into account sight radius that will give you the exact 2:1 ratio?
There is a formula, but I can't remember it. If you give the width of the sights, and the distance apart, I usually just put it in autocad. I like to cheat like that...
Ok the sight radius of the HK is 5.6", the front sight post width is .140" and the rear notch width is .168". I like this ratio or sight gap alot, am very used to it. works well for carry and comp. The new M&P that I want to change around to match the HK sight picture has the following dimensions: 6.4" sight radius, front post width of .130" and rear notch width of .140".
Scott Warren makes his rear sight for the M&P with a .150" notch width and SpeedShooterSpecialties will make a custom width front sight. So if you can punch the numbers please let me know what I need (want).
Thank you
