I doubt anyone makes a gun-specific "tactical" holster for a plinker. And if I recall correctly, you have a dot sight on your P22, which pretty much eliminates all the thigh holsters I'm aware of. If you take the dot sight off, you might find one of the Uncle Mike's (or other nylon generic fit) "tactical" holsters that will work with it.
Having used a Blackhawk thigh holster here in Afghanistan for a time, I have a pretty low opinion of them for anything but very brief periods of wear. They are okay if you're wearing bulky, hard body armor and can't use anything else, and you're not walking a lot. Using one while stalking small game all day will very likely be no better than a decent belt holster, while being simultaneously less comfortable and more expensive - and definitely sillier looking.
