The Default Secondary Weapon Change - USP is a Special Item that can be bought in the Black Market. When bought, the Default Secondary Weapon (which is the M92FS, unless you bought another default secondary weapon) would be ultimately changed into the USP, thus allowing you to keep it forever.
Although this may sound like a good idea, it has a large price tag of 9,900 NX (an equivalent of $9.90 USD), although it makes sense for it allows the player to not worry about the weapon expiring and allows them to play less often and keep their GP from diminishing.
A Default USP
As of the 2-3-10 Patch, Default Secondary Weapon Change - USP along with the other Default Weapon Changes have been removed from the Black Market and are no longer available.
