I like Randy's philosophy with regards to ammo and magazine commonality.

1. Long gun:
Glock hasn't come out with a pistol caliber carbine yet so my pick is a Mech Tech carbine conversion kit for Glock in 10 mm combined with a Glock 20 frame. The only accessory I would add is a sling and maybe a light. I like Glock for their reliability and 10 mm because you can hunt with it.

2. Pistol:
Glock 20. Maybe a light. Reasons are reliability and 10 mm because it has good penetration for 2 legged critters.

3. Pack gun:
Ruger 10/22 takedown. If we could make this an NFA item then it would be integrally suppressed. No accessories. Reasons are portability and the amount of ammo that can be carried.

Iron sights for everything. Reasons are durability and I don't want to depend on batteries for my optics to function.

I made my selections based on the assumption that I am bugging out. If I were bugging in then my long gun selection would be different.

I do not own any of these firearms.
