Hamilton .45 Pistol is your default pistol when you start the game.
Standard-issue pistol with balanced traits.
The Hamilton .45 Pistol is the first pistol available to Michael Thorton upon leaving The Graybox. It is always available in the weapons locker in the Saudi Arabia Safehouse from the start, regardless of which Agent History is chosen. It is an average pistol and belongs to the basic "first tier" of weapons (unmarked with stars) and is the most well-balanced of any pistol in this category in terms of damage, accuracy, and recoil. It is dark gray/black along the body with black plastic grips and dark gray metal parts (slide, trigger, magazine, etc.).
These are the dealers who sell those weapons
