I carry my P6 via IWB when bowhunting and stalking, it's always on me when in the field. There are too many jackasses that even show up on private land such that I won't hunt without something like that on me. Keeping a suppressed pistol in my pack is a nice option when I have a big(ish) pack but for bowhunting in a treestand the climber takes that space and I keep a small chest pack that's big enough to hold a grunt, compass, spare knife, lighter, map, etc. Nothing big enough to put a suppressed pistol into.
IWB on the carry pistol has never gotten in my way while hunting. Not really tacticool but it's about the cleanest thing that I've found to make sure I have something on me at all times, it stays under my clothes and while readily available it's also prone to drawing less attention when I invariably run across the local Barney stomping through the woods trying to find truant teenagers that are getting stoned.
