I'm trying to fix up a 1940s-vintage small-frame Llama.
It needs at least one grips screw, though I'd buy a hundred to get that

I have 5 of these guns, and most of them have some buggered slots, or
threads or both.

The screw I need measures at M3 x .7mm, 5mm long I think I can also use
5-36 US.

Both of those appear to be like hen's teeth.
If I can get the thread, I can adjust the length and the head diameter.
Need to be slotted pan heads

I have looked at MSC, McMaster-Carr, and Fastenal.
I have also dug through my lifetime accumulation of little fasteners
until my fingers are raw.

Any suggestions on where I can source those?

These probably won't pan out, but:

Amazon bought out Small Parts, and still has some of the good stuff.

Also try:
