The Colby Master is the standard issue pistol for the Agents. It is a semi-automatic pistol equipped with an electronic magnification scope for long range shooting. It fires 5 rounds per second and takes two seconds to reload when wielded by a professional. Its bullets can bounce off of walls to hit enemies. Agents such as yourself may tend to revert to the usage of other, more heavy firearms. It doesn't return in Crackdown 2 like all pistols from last game.
The Weapon Looks Like a Heckler & Koch MK 23 With some elements of the M1911.
