I'm looking at an SM57 that has a 3-mm gap between the "head"
and the body through which you can see a fine black square mesh.
The mesh does not quite cover the circumference : there is a 1.5 mm
gap.

Whatever is behind the mesh is elastic. If you press on the
head, you can narrow the gap to about 2 mm. If you pull, it
looks like it could come apart.

Is this normal ?

Yes, that is the rear port that allows it to be directional. The
movability is the elastic capsule mount that reduces handling noise.

Yes, that's a very good description of a SM57. Perfectly normal.

Yes, the rubber "shock" mounting between the upper body sleeve
and the cartridge has some play and they are sometimes loose
and sometimes a bit tighter. If it really bothers you, you can get in
there and tighten it up a bit. It's normal, though.

ALL SM57's by definition are totally weird. Just LOOK at them FFS ! It's
not quite a 1930s design but getting on that way.

Avoid it at all costs. It could cost your career unless you have exactly
the right value resistor.

Better dynamic mics by far can be had from the wonderfully enlightened
European shores including mics by companies like AKG and Sennheiser.

Consider condensers, and the world's your oyster with the likes of
Neumann and Schoeps.
