Wirehaired pointing griffons would be great for what you want.
They have tremendous all day staying power when you're out hiking/hunting, and when you're not they are pretty content with an hour or two romp or day long access to a large yard, and happy to settle down in the house.
This is very unlike most other pointers. GSP and GWP have endless energy, no off switch whatsoever. The brittany spaniels I have met were the same way.
Also, some of the gun dogs were bred to work far afield, flushing and pointing game. WHPGs are a close working breed. Charlie has taken very little recall training to become reliable. It's bizarre, but out in the pasture/fields/woods it is like he is on an invisible line. He will trail out to the end of it, about 50-60 feet out, and then come zooming back to check in with us every 5-10 minutes. This is how they are bred to work, if you read the french working standard. They are rare enough that it is easy to find a good working bred WHPG with correct style in the field.
They are also cool to hike with, because they point naturally and creep as close as possible to the bird without scaring it away. Charlie points quail and grouse that we would normally walk past, so we see more wildlife with him around.
They do very well in all kinds of terrain. They have huge rubbery feet to keep them from sinking in deep mud and the perfect coat for traveling through brush and stickers. Charlie is WAY strong. Robert tires him out by throwing branches down a 25 foot waterfall near our house. He runs down a near vertical slope, grabs it, and runs back up again. His muscles are awesome.
They are smart, durfy, and extremely handler focused.
Another big bonus, is dog aggression of all sorts, including same sex aggression, is unheard of. Out of the 12 breeders we contacted, every single one said that it does not exist within the breed. That was a huge factor for us getting one.
