Hello. I have not really looked into much in that weight for .45 ACP, but will be doing a test on the new Corbon DPX 185-gr. +P hollow point in the near future.
I have not personally tested these and know of no one who has used them on either animals or felons, but I believe that Remington offers Golden Sabers in 185-gr, both at standard and +P ratings. I've had good luck in recent times with Golden Saber in 230-gr., but have not worked with the 185-gr.
As you mention "hunting back up", you might take a look at Hornady's 200-gr. XTP. It can be had at both standard and +P velocities and is normally a very accurate load in most pistols. I've killed a deer with the 200-gr. in a handloaded equivalent to the +P and got complete penetration on a broadside shot. I know this is a bit heavier than the 185-gr. weight you specified, but it might be worth a look.
Best and good luck.
