The poster above that said Glock 29 is spot on. A concealable 10 mm. It meets all your requirements.
However, I have to agree that this whole idea is a compromise. It's hard enough to handgun hunt with a full size pistol, nevermind a subcompact. And a hunting-power cartridge in a CCW would have it's own set of problems: over-penetration, uncontrollability, etc.
I think you'd be better served with a subcompact pistol in .380 or 9mm, or revolver in .38 special for CCW, and a separate .44 mag revolver for hunting.
The 29 can do both, but is the best at neither. If money is the issue (it often is with me), choose the need you most immediately need to meet, and find the gun that meets that need best for you. The secondary need can come later.
But if you must keep it to one gun: Glock 29.
