Anyone have an unneeded lvl 50ish Infintiy pistol?

I’m trying to level by shooting the vandal in Sanctuary, but my infinity pistol is level 33 (i’m 53) so it’s pretty inefficient. It’s taking me about 5-6 seconds for every kill because he comes all the way to the front of the room before I can damage him enough and then the delay of it going backwards than forward again is so long. I’m hoping with a properly leveled pistol I can get that down to about half and level a bit faster. Ran the Frosty boss about 20 times today trying to get it to drop but no luck.
If you can help please message me on XB1: Carsonova
