I remember someone saying it has something to do with the safety type. In particular Im refering to the FNP 9 FN Herstal. There are two stainless steel versions on impactguns.com

-FN FNP 9 'USG' 9mm, Double Action/Single Action, Matte Stainless, 16rd Mags

-FN FNP 9 9mm, Double Action/Single Action, Stainless Steel, 16rd Mags

The price difference is $10

Thanks

According to the FN website the FNP9 comes either with or without a safety. USG, which probably stands for something like U.S. Government, probably has the safety, as that's usually required on military sidearms. That's the only difference I can see.

I have an FNP-45 USG. It has the same decocker as the non-USG model, but the lever can also be flipped up in SA or DA (hammer back or hammer down) mode to disconnect the trigger.

The USG model has a red dot under the lever and front cocking serrations on the slide. Easy ID at a glance.

AFAIK...
FN uses the USG designation to denote it was made to meet the specification set forth from the last US military RFP for a sidearm.

On the USG model, you can carry the gun cocked and locked. The regular version only has a decocker.
