Beretta Model 93R, "R" standing for Raffica which means short burt in Italian is a selective-fire machine pistol.
The 93R was designed in the early 1970s and meant for military and police use, offering extraordinary firepower in a small pistol. It is ideal for concealed carry purposes such as close quarters fighting, VIP protection, and room-to-room searches.
A foldable foregrip and a selector switch on the firearm allows the pistol to fire three round bursts with each pull of the trigger for a full potential cyclic rate of 1100 rpm. The designers of the 93R limited it to three round bursts to allow the weapon to be more easily controlled. The 93R is essentially a Beretta 92 series pistol (the Beretta 92FS is termed "M9" by the US military, and is the standard issue pistol for the US Army). But the 93R firearm is single action and outfitted with a direct muzzle brake, an optional detachable shoulder stock and an equipped 20-round magazine that also allowed for a firmer grip. The weapon is currently out of production.
