I put a model 1879 buckhorn trapdoor sight on my sporterized trapdoor. I like the sight because it has windage adjustment, and I think it looks a lot better than the Buffington. However, for some reason I am havin trouble using it. I think the problem is that the rear notch is too small, but I have used that sight in the past without problems, so I am thinking that maybe the problem is that my eyesight isnt what it used to be.  The front sight is a silver blade. I tried a modified buckhorn with an extra wide notch, but the notch is too wide. Before I waste a lot of time making and modifying sights, are there any standard criteria as to how to match up a front and rear sight? The darn front sight is too hard to see right now, and I dont know if its too wide or not wide enough or if the rear notch needs changing or what.  I am posting a photo of the Hawken style buckhorn that I added to the original US Army buckhorn, which I think would be OK for hunting by the notch is too wide for target use. Right now the original 1879 buckhorn sight is on the rifle. Thanks! Joe S

I would replace the buckhorn with a simple square notch.
