Yes. Although the Police force in the Republic of Ireland - 'An Garda Siochana' - is generally unarmed, approx. 1 in 4 members are licensed to carry firearms.
Practically all Detectives are armed with semi-auto SIG Sauer P226 9mm pistols, or concealed 9mm self-loading Walther P99 compact pistols. Plain clothes officers have the option of carrying handguns. Specialist Detective units, such as counter-terrorism teams (Special Detective Unit), routinely carry the Heckler & Koch MP7 submachine gun, and are also equipped with assault rifles and sniper rifles. Armed Intervention teams - Regional Support Units & Emergency Response Unit - are also heavily armed, and posses specialist equipment such as Tasers and bean-bag guns.
Still, the uniformed Guard you meet and greet on the street is unarmed, apart from their baton and pepper spray. Managment is considering arming all Garda officers with Tasers in 2014.
