Question about the front sight. It certainly isn't original, much taller likely so the target shooter owner could shoot at shorter ranges, and it's longer then the base. The pin is missing, easily replaced, and it looks like the blade, which is .0490 thick, seems to be either soldered or welded in place.
My library tells me the originals were .090 thick at the base, and a variable thickness above the base. So that makes sense then, and I don't think the groove on the base was messed with.

I would like to remove it, make shims for it's bottom half to fill out the groove, and pin it so I can put an original back in if I wanted. I don't like it being permanently fixed with no pin. Question is, does that look like solder or a tac weld? I don't weld, so forgive me.
