I just picked up my KKJ in 22LR--fine condition and great shooter. The serial number indicates 1960 manufacture according to data on this site. The front sight band and trigger guard could use some touch-up while the rest of the gun is immaculate. Here's the issue: I'm having trouble removing the front sight assembly. The forward facing screw comes out easily freeing the front sight blade, but the smaller screw behind the blade on top of the ramp base refuses to budge. It will move slightly right and left but that's it. I've tried penetrating oil but it still won't move to the left more than a fraction of an inch and I really don't want to snap it off. The other issue is the hood. It's slightly bent to one side and so sits on the base tipped to one side. Any ideas as to how to straighten that out and get that band off? I've checked various archives but no luck.
