Forum:Few Questions...

Alright I just have a few questions i'd appreciate if anyone can help. 1, I was wondering how to get the Level 10 Storage item at Mad Moxxi's. 2nd, I got a SVS30 C COMBUSTION HELLFIRE - 312 Dmg - Acc 93.5 - F.R 13.8 - x4 Fire Chance - and 19 Ammo Regen, This weapon was given to me while playing with someone random in a stage in Mad Moxxi's and he gave it to me, im guessing since I was always almost about to die, and I was wondering if anyone has seen one like this, or could it be modded, BTW sell price is 3,183,210. I had another question but my mind went blank. Any info/opinions would be great. Thanks
