The PP9i is one of the "Classic Weapons" featured in Perfect Dark. It is essentially a duplicate of the PP7 Special Issue that appeared in GoldenEye 007, and which is itself based on the Walther PPK. Statistically, it's quite similar to the Falcon 2, but has one bullet less per magazine. On the other hand, the reload time is a fair bit lower.

Perfect Dark (N64/Xbox 360) Edit

As a classic weapon, the PP9i has no secondary function, and there is no in-game description.

The use of the PP9i in single player is unlocked by getting gold medals in the firing range, as with all classic weapons. Alternatively, the All Guns in Solo cheat will also give you all the classic weapons.
