I'm gonna approach this as 5 total for the hell of it.
1) Ruger 10-22
2) AR-15 in 5.56
3) Synthetic stocked, 24-26", 12 gauge Remington 870
4) Glock 17 or 19 or 3-4" stainless revolver in 357 or 44 special - This one really depends on whether you'd want it for outdoors carry.
5) Bolt action hunting rifle of choice in either 300 win, 7mm rem, or 375 depending on how far reaching your hunting plans.
Funny enough but I don't own half of this list as I tend to have more specialized guns since we're not this limited!
