chucky goes to the closest weapon he can find
gifts, weapon shop, tournament or you find them on the battlefield
if you sell your weapons you have two options one is that you can buy the weapon back and the second option is that you will have to find a chest with the weapon in it or then theres a third option is that you can spawn the weapon with cheats or hacks
you have to find them orget them from qeusts (i get alot from red weapon cases)
you don't get the weapon parts. You find documents in missions and extra ops to build your weapons.
This type of weapon is usually a random drop. Or you can find them randomly for sale at weapons vendors. Alternately, you can create your own at an enchanter table.
You cant make weapons in borderlands, you find them, (i finished game)
if you want to enhance weapons just go to battle on and click enhancements on the little menu on the right
Under standard button configurations, the 'z' button will sheathe or unsheathe your weapons. It will bring out your main weapons first (so melee weapons or staves), then ranged weapons and wands, then cycle back to unarmed. If 'z' does not cycle the weapons, hit escape and go to Keybindings. Find the Sheathe/Unsheathe Weapon toggle and see what button it is bound to. Bind it to a different key if you prefer, or set it back to 'z'.
Hit your select button, move up one to "Equipment," select "Weapons" and find the weapon you want to wield and select it, it will give you a "Wield" option.
If you want weapons in a certain non-weapon game, you're out of luck. However, if you mean when you're building, that's a lot easier. The best weapons, but also the hardest to find working, are on the "Free Models" database. You can get to this database by clicking the "Insert" button on the "build" or "edit" modes, then scroll down to the "Free Models" menu, and search for the weapon you want.
You can get weapons at any shop. You need gold (which you can get as quest drops or from monsters) or maybe coins called Adventure Coins, which you have to buy to get it. Go to a shop, click on a weapon and click Buy. You will find it in your inventory. To make it stronger, you can enhance it. Go to Twilly, find the enhancement suitable for you (I suggest Hybrid) and click on the NPC which has enhancement. Find one enhancement, buy it and apply to weapon of choice. You can also get weapons from monsters or as quest rewards, but you have to enhance it. Follow instructions above.
