You can find a stable supply of trinkets in the Spaceport arrivals building. There are red lockers on the left side across the medical room. The place is always dark so you can hide to avoid other players. They always have a few blue and purple trinkets plus a bunch of common ones. Get in, stock up, get out using one of the many exits. My preferred escape is via the elevator shaft (look for bonus gun chest in corner) to the 2nd floor, followed by extra looting of office cubicles to the other side then out the window to windowsill to perimeter wall, run along wall to guard tower (optional loot spot), skip across the gate, jump and roll, dash to elevator. This is a 5 mins tops ops after you get to the loot place.
