FREDDIE'S NEW GUN: The Ingram is noted for its rapid rate of fire -- so because of this it's regarded as highly dangerous when used in untrained hands.
Ingram Model 10 and Model 11 weapons are intended for close encounters and for concealed carrying. The Model 10 takes a 9mm Parabellum cartridge from a 30-round box magazine and has a rate of fire of 1145 or 1090 rounds per minute.
THE ERU GUN: Emergency Response Unit officers carry a Heckler and Koch MP7 personal defence weapon -- a cross between a submachine gun and an assault rifle. The MP7 has a rate of fire of 950 rounds per minute and a magazine capacity of 20 or 40 rounds.
It fires tiny 4.6mm x 30mm bullets, designed to penetrate body armour from a distance of up to 200 metres.
But regular garda detectives use a SiG P226 9mm semi automatic pistol, less powerful than the Ingram machine guns found.
And the garda's standard submachine gun is the 9mm Uzi but it will not defeat modern body armour with its normal "ball" ammo.
The ERU acquired the MP7 after Dublin and Limerick criminals routinely started to wear flak jackets, while Limerick criminals also imported armoured cars from Europe.
It has a 40-shot magazine holding special 4.6mm x 30mm bullets capable of slicing their way through body armour and helmets at up to 200m.
