I found a pistol on the floor, loaded a mag, and it worked, so this problem would seem to be when looting the pistol from bodies

I forgot to mention, I tried with 2 different pistols, both didnt work

I had this issue too, I got my pistol from a body also, loaded pristine rounds into a pristine magazine, loaded into the fnx45, it just makes a clicking noise.
