You have to be picky to successfully manage your inventory. I only carry around 5 weapons, 6 at the most. Sometimes I have my fav 4 and stick to those 4 at all times. I play favorites with grenades too, and almost always sell grenades unless I get something better. Shields are also shop fodder until I find something better.
Also, when it comes to keeping guns for other characters, I only keep guns that are almost overpowering, and save those in my shared bank, or any character's bank, for future playthroughs. If they are okay at their level, then sell it or chuck it, only the strongest survive.
I'm much rather have money for slots and "items of the day" than too many guns in my inventory.
You look under puppy's message. You find a potion!
I don't care about collecting guns or anything, so I just sell guns if I'm not using them anymore. I generally like to have around 15 slots filled out of the 27 before I go farming or on a mission or whatever so I have plenty of room to pick up new guns and decide what I want to keep.
This is generally what my inventory looks like:
Fire sniper *(rarely gets used/not always in inventory) Corrosive sniper Shock sniper Non-elemental Jakobs sniper
Apparently no one is listening when others say unlimited space in your bank. Step1. Open Bank. Step2. Highlight item in backpack by pressing A. Step3. Highlight another item in your backpack then press A. ( You will notice item #2 is in your bank) Step4. Repeat til only 1 weapon remains in your backpack.
Congrats, now you have unlimited space. Works with a characters so, no need to use claptrap bot to move storage around.
Reply if you got it to work.
