An easy drop question

[Aslan]

I'm trying to put an ASA on one of my drops but the drop is missing the little set screw that hold the ASA and drop together.

Any idea what size those are? Or are they different sizes? If I went to the local pb shop, you think they'd have a bunch of those laying around or do I need to start searching specialty hardware stores or something like that?

Thanks

If they are the same size as the drop to grip-frame screws they should be 10-32

No...these are the small set screws that go down and hold the ASA on the drop. If I can't figure it out, get an answer...I'll post a pic.
