I found as I got older that I was having more difficulty getting a good sight picture at night when trying to shoot with the aid of a flash light. A black bear in a tree does not reflect a lot of light.
I put a green laser on one of my side arms , it makes hitting targets in the dark much easier, so far I have not had the opportunity to try it on any predators. I also made a holster, putting extras on handgun makes for a few less commercial holster options.
