It was winchesters little ballistic comparison graphic-tool that made me come to the same conclusion pb.

Of course, to be fair Winchester's .357sig is loaded south of it's potential, at barely 100fps faster than their 9mm +p+. Although if you look at DT, they get the same bullet weight up to 1400 fps (though no penetration/expansion data, so who knows what it's really adding).

Nonetheless, despite that, and the fact there are things I like about the 32 over the 19 (the new melted corner slide like on the prac/tacs and subcompacts; and as said its beefier- designed to eat essentially +p+ all day; AND you can barrel swap to shoot 9mm from the 32 anyways)- I'd STILL make it a 19 at this point.
