OK. I went to the gun show and didn't find any deals that quite matched this (although I did come really close to buying a Colt 1903 from 1914 and a Mauser C-96). I left the gun show and I went back to the gun store and got the Glock.
It's definitely a Gen 2. It's from 1996 (the box had the original sales receipt in it).
Here's everything it came with.
Tomorrow, I go shoot it.
