Sigs are all test fired, as are Glocks. I have a Glock 17 around here somewhere. It came with a little manila envelope in the case that contained two empty cartridges from the test firing.

As I mentioned, coming dirty from test firing at the factory is no big deal. A quality combat weapon will run fine dirty. I clean my pistols and rifles, but only every so often. Maybe every thousand rounds for pistols and every 2000-3000 rounds for rifles. A precision rifle...that I might clean more often, but in a combat weapon I'm more concerned about function than I am about precision and a Glock or Sig, or any quality AR15/M4 will run fine for thousands of rounds with only some quality lube and an occasional bore snake. AR's have a tendency to accumulate carbon around the bolt tail, so periodically I'll soak them in some CLP or maybe some kerosene and wipe them off, or maybe scrape them. That, and an occasional chamber brushing and any quality AR with an in-spec chamber works even if absolutely filthy as long as they're lubed.
