Been there.The standard sidelever Diana front sight blade is wide enough to completely block a jackrabbit sitting at 40 yards. It could be used for digging trenches, though.From my research, it seems globe sights fitting the sidelever line were last available around 2010. I had no luck finding one.My CCA D54 has a standard, level front sight dovetail and a standard globe sight on it. Boy am I glad to have that. For my D52 Luxus I'm going to thin the factory blade, with some judicious Dremeling and filing.
