TPS Storm Front Grenade mod

just wondering if this mod is on the pre-sequel and if so how to get it

Yes, got 2 over time from farming the vending machines
also had a Guardian drop 1

believe I have a spare homing one level 70 if you like. GT:StoneOrpheus922

Yeah I’m level 22 but 70 on borderlands 2 and I can just walk thru the maps and bosses with it. But okay the handsome collection tps, just always check vending machines and check drops?
