Somewhere along the lines of the game, near Memory Sequence 10 or 11 (I think) you will receive a codex after an assassination. Take this to Leonardo and he will outfit you with the hidden pistol.
For Assassins Creed 1 No, for Assassins Creed 2 yes.

Assassins Creed II
Assassins Creed Bloodlines is 5 weeks after Assassins Creed 1. This is what happened to Altair before he dies. Assassins Creed 2 is a completely different thing. The main story is the same but the story of the main characters, Altair and Ezio, are very different. Assassins Creed Bloodlines does not have the Animus in it as much as Assassins Creed 1 & 2
