When trying to put a FNX45 in a chesthoslster, I encoutnered the issue that it would not want to go in the holster.
THen i tried putting a magnum in as a friend told me that his FNX and magnum fit in fine.
The magnum fit. After removing the magnum, the FNX fit too.
5 minutes later another friend had the exact same issue, while two others did not have it at all and could use their hoslter for the FNX straight away.
- all items were pristine in my case. not sure a bout the rest of the players.
