Psycho, we need a whole lot more information before this question can be properly answered. For instance:
1. Under what terrain conditions do you hunt? If there's a lot of thick brush, thorns, etc. through which you're moving, a full-flap holster might be a huge benefit to protect the handgun from scratches and twigs, leaves, etc. being deposited in the holster with it. In more open terrain, or in a stand, this might not be necessary.
2. Do you need to be able to draw the weapon quickly, or would this be a more leisurely requirement? If the former, forget something with a safety strap; if the latter, a safety strap might prevent the gun being dislodged from the holster while you're moving (especially in thick brush), and might be an asset.
3. Do you need to access the weapon while carrying your rifle slung? If so, where do you sling your rifle (i.e. on which side of your body)? You don't want your holster on the same side of your body as your rifle, where it will bind on the rifle sling and either impede rapid deployment of the rifle, or the rifle may impede rapid deployment of the handgun, depending on the situation confronting you.
4. Is the weapon intended solely for backup while on foot, or will you perhaps consider it a personal-defence weapon while driving to and from the hunt? If the latter, a cross-draw holster, in front of your hip, will make it much easier to access while sitting in a vehicle, whilst still providing secure carriage of the weapon while hunting.
5. Do you have back problems? If so, slinging a heavy revolver on one or the other hip might aggravate the situation. For such a condition, I'd suggest a cross-chest-slung shoulder holster like those made by Uncle Mike's or other outfitters. This is supported on one or both shoulders, rather than the hips, and imposes less strain on the back.
I could go on, but you get the idea. Please tell us more, and we can then give more appropriate advice.
