Around 25 lives have been saved since the city's armed support unit hit the streets.
It was set up in December in light of a gangland feud.
The dedicated garda Armed Support Unit is responding to almost 3 serious crimes a day.
The 55 strong unit was set up to patrol Dublin's streets after the Hutch/Kinahan feud claimed 11 lives in just 15 months.
In a three month period, the Armed Support Unit, which operates 24/7, has been responsible for saving around 25 lives and was called out to 248 serious incidents.
The incidents were not just linked to the feud, but included crimes involving guns or gardai stopping a crime from being committed.
Justice Minister Francis Fitzgerald told the Association of Garda Superintendents conference that the unit had struck repeated blows against organised crime in the city, led to a reduction in crime and increased public safety.
