Actually, I recall one of the unreal games having a gun you shot a teleporter beacon, then could teleport to it or from it or something like that. So there WAS teleportation creation in them, and from a gun nonetheless!
Heck, Team Fortress Classic had buildable teleporters (granted they weren't added until a while after the game was released, and not from a gun) the engineer could build.
I'm sure one could find buildable teleporter examples in even older games, although they might not have been FPS. I bet there were teleporters in old amiga games for instance
