Here's a Four Step strategy for quickly taking out Hordes in Days Gone, no crafting required.
Additional note from u/SpawnicusRex in r/DaysGone:
Frag Grenades are available from all merchants (at least 1 or 2) but Flashbangs, specifically, are not sold at Copeland's or Tucker's camps. Can't get those until Iron Mike's camp unless you're picking them up from rare locations where they respawn.
