Anybody have any experience with any of the all black sights offered from Warren Tactical/Sevigney, Heine, or 10-8? I prefer and all black sight picture and am thinking of getting one of these systems for my 34. Any personal experience with the above listed brands, or possibly others I missed would be appreciated. Especially interesting would be the front sight height you used to get good top of front sight/center target holds. I will primarily be using the 115 gr factory cheap-o stuff and evidently you need to have the corresponding height front.
