Ok, so I'm doing the part of Contreras' mission where i deliver the meds, but when I get to the pawn shop the doors are locked with no way in.
I really want the unique M1 that he give after the quest.
So I wanted to know if there was a way to fix this at all or maybe where to find a regular M1.

I can't get in the pawn shop either. It shows me there is a door but the door does not give any options to open it. Is there another way in or something?

It's that white door right inside the Westside entrance .

Just to clarify in case you guys do not know. The Pawn Shop is within an area called Westside. There's a white graffiti that reads pawn shop outside its wall, and the first time I arrived there a mutant was standing outside.

Yup, that's the one. As I said I go right up to the "there is a door here" marker on the local map but get no options at all to enter on the door itself.

Anyone else know anything or had issue with this?

i have this issue. dunno what to do

Ok so the poster that said in another post about this was right. If you crouch in front of the door and go into 3rd person and just slowly look around the door the enter option should come up. Worked for me anyway.
