Would anyone know the width of the Heinie Qwik S8 front for the P30 found here.. http://www.heinie.com/product_info.php?products_id=172 I see that the rear notch measures .156 wide. I have a set of S8s and am curious if the FS width is the same with the only difference being the rear. I will measure the front sight width on mine in the morning for a comparison.
