I need 2 rear sight screws for my model 8 with a rear flip sight, the heads on the regular sight screws are too large so they don't work well, I need screws with a head size of .250!

Iceman,I've had the same issue before and haven't been able to find any screws that fit either. I'm in Iowa,home to Brownells. I just need to go over to their shop and find out if they have any thing that will work. My work is just too busy to take a day off to find some screws. Maybe when it slows a bit, I'll get over there. If you find some ,please let me know.my email address is in my signature box below.
Thank you for your time,
Roger

IceMan,
You might try Williams gunsight, they made a dovetail block for the hinged sights, it used smaller diameter screws (recessed). They could have some screws stashed
