If I was just starting out or single I might be a one gun multiple purpose guy. Why if I was single? Because I would live on 40 acres instead of a smaller property in a good school district, and I would feel a lot more comfortable with a lever action, shotgun, or AR carrying around the property and keeping nearby in the home, whilst doing everyday tasks. As it is with a family around I don’t have that comfort level nor do I need it. When I say I would feel comfortable, I mean from the perspective of safety with kids running around, not from the perspective of “i’d be uncomfortable in my backyard without a gun”.
As it is, because I can’t have that close a relationship with one long gun throughout my waking hours:
What I do is EDC, whenever my pants are on (whether relaxing at home, shopping, etc) a G19. It’s in my bedside safe at night as well.
12 gauge and 20 gauge are for hunting. Deer in front of dogs, small game, doves. Clay shooting.
The AR has finally had a RDS added and a rail mount flashlight will be delivered by the brown truck tomorrow and it will be (as it is now) in the safe with full mag and 3 loaded mags for HD purposes or if a coyote comes by the chicken coop.
Muzzleloader obviously has a specific deer season purpose and as I live in a ML only area, it stays loaded no primer all fall long for backyard deer opportunities (got one from my bedroom window this Thanksgiving).
Tikka T3 7mm-08 is my medium game hunting rifle when I am not with someone running dogs (my hunt club and public land is where I tree stand hunt).
22 Model 60 is for training, Appleseed style, with aperture sights at 25M in the backyard.
22 Marlin 25 w/ Nikon 4x is a dedicated
Coon rifle.
M1 Garand is a range toy.
So I would say none of my firearms are really multipurpose. Sometimes I fantasize about if I did have “one gun to do it all”, a lever 30-30 or AR in 6.8 variety maybe that was next to me whether I was in bed or riding the truck to the hunt club. As it is, not gonna happen.
