In No particular order....
SIG P229R in .40 S&W

A Rossi Lever action .357 carbine with a 16 in barrel. Preferraby in stainless. Maybe with a big loop lever.
Charter Bulldog .44 SPL. May never get one, due to the price and availability of Ammo.

Ruger LCR in .357.
KAHR PM45

Stoeger Coach gun

I've got more I'd like to have. But may never get.... Stoeger Double Defense, GLOCK 35..... I'll come back and add more later.
Something I may get, is a 10 MM conversion barrel and some G29 mags for My GLOCK 30.
