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....

Ayup. Wierd sizes are more expensive than normal made by the millions

"First Law of Leftist Debate
The more you present a leftist with factual evidence
that is counter to his preconceived world view and the
more difficult it becomes for him to refute it without
losing face the chance of him calling you a racist, bigot,
homophobe approaches infinity.

This is despite the thread you are in having not mentioned
race or sexual preference in any way that is relevant to
the subject." Grey Ghost
