Garreth , I can't say that I've ever looked at the holster that comes with the FX suit , but the ANH Elite standards only have this to say :
# Holster is worn on the left
# Holster must be attached to the belt from behind instead with no loops covering the outside of the belt
Unless it looks like a total piece of rubbish , and it doesn't comply with the standards , it should be ok . Of course , if you get one of the snazzy holsters you can get from some of the blokes here , you'll probably be happier with it . Remember , you can always upgrade later .
