Load up your main character and add the second profile character to your group. Give them some cash then save and exit.
Load up the second profile character (only them or it will skew prices) again and Fast Travel to the Holodome. In here you will have your first access to a Gun vending machine (two of them actually, one at the start and one inside the Holodome). You should be able to buy (at a cheap price) and hold 14 white items at a time if there is 14 on offer (12 + 2 equipped). Save and Exit.
Load your main profile also adding the secondary profile then goto Triton Flats for the quest. Trade the weapons and progress through the quest normally. Rinse and Repeat 4 times. Fastest way I've found to get the weapons without a lot of save exit farming of chests.
For those of you importing a character from the 360 you won't unlock this if you've already completed all of the side missions during your Normal playthrough. You'll either have to start a new character and do all the missions that way, or like I had to do, finish up the remaining ones from my True Vault Hunter playthrough. It'll save you a ton of time if you have one in progress.
There's no need to do all of the DLC missions.

You get side missions from various characters that you meet along the journey, as well as from mission boards. Whenever you notice a yellow exclamation mark on your map you should investigate it immediately as it is a side mission. You do not have to do them right away but if you pick them up as soon as you notice them you'll have them in your journal ready to complete.
Some of the side missions will appear in your journal as 'Undiscovered' so you know that you need to go and pick it up from whichever area it is in, but not all of them do this. You should check back through all of the areas every so often to be sure there aren't any that have become available without you knowing.
Note that some side missions take you to certain areas that you otherwise would not go to, so doing them all ensures that you get all of the secret areas for the achievement 'Cosmic Completionist'.

NOTE: The mission "Picking Up the Pieces" is located in the Lunar Launching Station, NOT in Research & Development like the game says.
GLITCH (AND SOLUTION): There seems to be a possible glitch with balancing missions between other people's games. The host of the world you're in will get the achievement, but you won't. This has affected some players who have completed all missions, but not everyone. If you want to keep playing with your friends or co-op partners and don't want to suffer from the glitch, you must turn in the final mission in YOUR OWN GAME. Turning your final side mission in other people's worlds seems to be what is causing the glitch to occur for some people.
