The following weapons were used in the film Manhunt:
Pistols
Beretta 92F
Several characters held a Beretta 92F.
Beretta 92F (Early Model) - 9x19mm (Other side showing "92F" on slide) Other than the slim grip covers (the 92F is slightly different with a gloss black plastic, versus the 92FS) the pistol is difficult to tell apart from a 92FS. The only real proof is the year a movie was made and whether or not the 92FS existed yet.
Beretta 92F Inox
Beretta 92FS Inox (flip side) - 9x19mm
Beretta 84
Beretta 84 (earlier version with round trigger guard) - .380 ACP
