The trigger guard on this kids' Savage Arms shotgun attaches with
screws
(which are missing). The thread looks like 10-32, but becomes hard to
turn after appx. 3 turns. Is that possibly a weird thread, or is it
just
designed to hold the screw tightly?
It probably is the standard coarse metric size 5mm x .8mm.
Note that 10-32 major diameter is 0.1900" or 4.8260 mm
and spacing is 1/32" = .03125" = .79375 mm, fairly close
to 5x.8mm metric.
An M5 screw in a 10-32 hole acts like what Iggy describes, but a 10-32
screw is a sloppy fit in an M5 hole.
I just remembered...10-36 is a rather common gun screw size.
as is 10-40 and 10-48

Its probably a 10-36
It should be noted..that gun screws are Seldom "common" sizes in thread
dimension.

As an example....
