In case you didn't know, that G32 is a .357 Sig, not to be confused w/ a .357 (S&W) magnum.
While the .357 Sig is a necked-down .40 S&W and is a fine SD cartridge, it is not an ideal woods cartridge.
It was designed to reproduce the 125 gr. .357 mag ballistics out of a 4" Bbl.'ed Auto and it does a pretty good job of doin' just that. But that is about all it does.
You will be hard pressed to find any suitable loads over 140 gr., and good luck finding any 180 gr.'s at all.
It is a "tee-shirt" round, and a good one.
Not too sure RE: the 10 mm out of a 3.78 Bbl. either. "Good enough" is pretty subjective. Some chrono data that clocks a 180 gr. bullet in excess of, say, ~ 1200 fps? would seal-the-deal for me.
That form-factor will get you a Glock 23 .40 S&W w/ a 4" Bbl. and an honest 1050 fps from a 180 gr. round.
I don't know what length Bbl. Underwood uses for their 10 mm tests, but they advertise 1300 fps in 180 gr. and that's what I get out of my heavy .357 mag Blackhawk-only hand-loads... and that's somethin'.
