I have 870 Remington with like 6 slugs mags and 7 pellets mags, 8 shells each. Also I have DMR with 6 mags in my backpack, 20 rounds each. And G17 as sidearm with 5 mags, 17 bullets each mag. But it takes so much space in my backpack so I only want to have one gun. It is so hard to decide because I like them both very much. Plus shotgun ammo is everywhere. Therefore I need your advice which one should I keep or just keep both?
