Beretta 93R

The Beretta 93R is a selective-fire machine pistol, designed and manufactured by Italian firearms manufacturer Beretta in the 1970s for police and military use, that is derived from their semi-automatic Beretta 92. It serves as Foley's secondary weapon in the first 3 missions.

Details
The Beretta 93R is referred to in game as the "Beretta Pistol Silenced". It is equipped with a suppressor, allowing for stealth kills. However, keep in mind that it has a low damage; it can only incapacitate Connors within four headshots, so aiming for the head might be necessary to kill enemies in one hit. Nonetheless, it also has a burst-fire option which allows it to be used just like SMGs instead thanks to its high rate of fire.

Trivia

 * The weapon's name, "Beretta Pistol Silenced", deviates from the regular naming scheme of "[Weapon] Silenced [Type]" (e.g. "Mk23 Silenced Pistol").
 * Oddly enough, despite having a built-in foregrip, none of the characters seem to use it, probably due to the game's limitations.
