I'll go by weapons obtained from the story in the first playthrough to the default and shop weapons in the first playthrough, then the weapons from the second playthrough and lastly to the weapons from the third playthrough. At the end, there is also a weapon overview.
Small Disclaimer: I've never collected all the weapons in Drakengard 2. So I can't technically confirm if the information from the guide(s) I used is correct. (Also, I used Apostrophes ( ' ) this time around)
Here are my Sources:

I used [1] for the descriptions of the weapon locations and [2] to see when a given free mission unlocks.
Free Mission = (FM) (Unlocked after given Verse)
Secret Free Mission = (SFM) (Unlocked after given Verse)
I did the basic overview for this guide a long time ago and honestly don't remember the difference between normal and secret free missions. So maybe it doesn't mean anything, but in case it does, I left the seperation instead of always labeling things free missions.
I recommend you to farm gold and experience at some point in your first playthrough (although you should also be able to buy weapons in the second/ third playthrogh). This is a weapons guide so I won't explain how to do it, but the first source [1] has guidance at the bottom of the guide ("Where can I level up my character?" , "Where can I level up Legna?" and "I looove Goooooold!" sections of the guide)
