I'm not exactly clear on what you mean by "surplus". Do you mean "used law enforcement" sold to the public, something the authorities took off an offender, or "new old stock" sold by CZ USA ? I'm clearly not up on these matters. I suppose it's the former, and that simply makes it well run-in, but still a modern firearm.
I'm not an expert, but to me all proper safety steps should be taken. It should be inspected by a competent gun smith, to make sure it hasn't developed any bad habits (like firing out of battery). Then, if the pistol shows any age or high round count, replace all the coil springs. Finally, any ammo used in it should conform to those appropriate for the model, which you can confirm by calling CZ-USA.
That's just my guess. For an expert opinion you'll want to talk to our resident 380Auto expert...
