Night Sight ID

I am looking for some assistance in identifying a particular set of night sights:

They are a set of tritium sights that have the standard two dot rear (no outline) and single dot front, along with two dots on top of the rear and one dot on top of the front. These were green tritium and did not incorporate fiber optics. I imagine the point of the extra tritium was to help with point shooting or unconventional positions.

These sights are issued to a friend of mine and he was not sure who makes them; they have no markings on them.

I cannot find pictures online and have spent the past several hours checking the major manufacturer’s websites…anyone know what I’m talking about?

Thanks

These are the only ones I’ve ever heard of that match your description, but they have fiber optics independent from the tritium.

I should have been a bit clearer- the extra dots are on top of the sights, facing up, so you would see them if you were to look down at the pistol from above. Not sure how useful they are but it’s been bugging me since I saw them.
