As far as I understand it's very restrictive. This is a summary of how it was about ten years ago:
"Anything vaguely handgun shaped is prohibited. Centrefire semi-auto rifles are banned. Rifles over .27" in calibre are banned. Firearm Certificates have a Irish L100 licensing fee, and a separate FAC is required per gun. Licenses have to be renewed yearly.
All guns require an FAC - even air rifles.
There may not be a requirement to be a member of a club or a training requirement expressly written into the law, but to get a license without being a member of a club is next to impossible."
I recommend checking with this organisation for the latest updates:
