1. 22LR rifle - 10/22 or bolt action. scoped.
2. .308 FN-FAL, 18" barrel. (removable) DSA scope mount and scope. Many full-cap magazines.
3. Glock 19, many full-cap mags.
4. Glock 23 or 27.
I would prefer to have 3 rifles and only one handgun, as a precision bolt rifle would be really useful for reaching out past where the FAL can be used.
The FAL is the workhorse - it can handle any North American game, and most social problems.
The .22 can be used for small game, and the pistols for self-defense.
The Glock 27 would be the main concealment pistol, and the Glock 19 is there just to have something that eats 9mm, which is ubiquitous.
As much as I love my AR-15, it just isn't useful enough in general use - besides plinking. It's good in "social" problems, but isn't powerful enough to kill much game reliably.
