I've been a Cop for nearly 34 years. I've carried all kinds of guns, on and off duty. I don't know you well enough to give you an answer. I don't know if you can 'Open Carry' where you're at or if you need to conceal your gun. How big are you? I'm 6'8" and 330. I can stick a SAA, a Glock 22 or a S&W 28 inside my shirt and it's concealed. I will suggest that you'd likely be best served by 2 guns. One powerful enough to defend yourself and small and light enough to actually carry. The second a fun to shoot, powerful enough to hunt with a 'Sport' gun. Might you find one gun to do both? I don't know because I don't know you well enough?
Also it's better to shoot someone with a gun that is as stock as possible with ammo readily available anywhere you go. In Court, it could go that far, you'll want to look as average as possible and not like a guy who was hunting a bad guy just to shoot'm.
