The average tricount for LOD0 must be like 2000. Some are more simple and only have 800 tris, other with lot of modelized details have 4000-6000 tris I think, I don’t have the exact numbers.
But note that most of them have champfers and custom normals instead of hard edges, that’s why the tricount is so high. And I’ve put a lot of tris in the rounded parts like the handle so it look smooth at close range. Then LOD1 approximately has half that tricount, and LOD2 has half the tricount of LOD1.
LOD0 is really made for when you get really close in first person view.
