So I have the choice and I'd like some opinions on which carbine to go with. Right now I have a m1 carbine .30 cal it's a us gi. And I have the opertunity to trade it for a nice decked out ar carbine .223. Well I love the little m1 it's a great gun and light and fun, but Ammo is not very common and neither are mags for it. I was thinking in a shhtf situation it would be hard to find Ammo or mags for were as the ars are so common you find parts/mags/Ammo anywhere you look. I know the m1 has a lot more value since its ww2 that's one reason I am also very hesitant. So should I do the trade thinking of shtf situation or just hold out and hope to find parts/Ammo for the m1?
