Well, my first thought is "it doesn't even have a hammer thong". I think I'll just follow this fellow and have a new gun when he drops it.
Seriously, I have a friend that did carry (with hammer thong) in a hollywood style holster similar to this while hunting. He dinged up a perfectly good buttstock by letting it bang against the butt of his hog leg with every step. He now follows my lead and carries crossdraw when hunting.
Now, if you are just handgun hunting, and want to do a fast draw on that buck, go for it. But, at least put a lanyard on the handgun so you don't loose it.
