Gun Safe Size Guide Ireland 2026: What Capacity to Buy
Share
Sizing a gun safe comes down to one question: how many firearms will you own in five years, not how many you own today. Wildhunter Gunroom stocks safes from single-cabinet units up to 20-plus gun capacity, and the right pick depends on your current FAC, your ammunition storage habits, and the space you have to bolt one down.
- Buy one capacity tier above your current firearm count to avoid a second purchase within two years.
- A 5-gun safe like the Griffon GLST-470-K suits most single-licence Irish collections with room to grow.
- Scoped rifles need extra internal height and depth that flat capacity numbers don't show.
- Ammunition stored in the same cabinet as firearms eats into usable gun capacity fast.
- Insurance and Garda inspection requirements often set the real minimum, not personal preference.
Why this matters
Getting the size wrong is expensive twice over: once when you buy a cabinet that's already tight, and again when you replace it two years later because your FAC now covers four more firearms. A gun safe is also a fixed, bolted-down asset in most Irish homes — swapping it out means new anchor points, new wall damage, and a second delivery.
Insurers and Garda inspections both look at secure storage as a condition of the licence, and undersizing a safe is one of the most common mistakes first-time FAC holders make in 2026. Buying capacity ahead of your collection, rather than matching it exactly, avoids that repeat cost.
What size gun safe do you need for your collection?
Start by counting firearms you currently hold on your FAC, then add any you expect to add within the next 24 months. That number, not your current headcount, is your target capacity.
| Current + planned firearms | Recommended safe tier | Best for |
|---|---|---|
| 1-3 | 3-5 gun safe | First-time FAC holders, single rifle or shotgun plus a spare |
| 4-6 | 5-6 gun safe | Combined rifle and shotgun owners |
| 7-10 | 8-10 gun safe | Growing collections, mixed calibres |
| 10+ | Large capacity cabinet | Established collectors, multiple licences |
The Griffon 5 gun safe sits in the middle tier and covers most single-FAC households in Ireland, with enough internal width to take a scoped rifle without forcing the scope against the door.
3 to 5 gun safes: right size for a starter licence
A 3-5 gun cabinet is the standard first purchase for anyone holding one or two rifles and a shotgun. Best for: first-time FAC holders who don't expect rapid collection growth.
The tradeoff is headroom — add a scoped rifle and a second shotgun within a year and you're back to shopping for storage. If you know your FAC application is likely to expand, size up now. Verdict: Buy if your collection is stable at 3 or fewer; skip if you're planning a second FAC application soon.
6 to 10 gun safes: right size for mixed collections
Once you're running rifles and shotguns together, or holding a rimfire alongside a centrefire, the 6-10 gun tier gives working room for scoped optics without cramming barrels against the door seal. Best for: licence holders combining rifle and shotgun ownership.
This tier also gives space to separate long guns from a handgun safely if your licence covers both. Read more on combined pistol and rifle storage before deciding whether one cabinet or two suits your setup better. Verdict: Buy for active collectors still adding firearms year to year.
10+ gun safes: right size for large collections
Beyond 10 firearms, capacity stops being the only variable — cabinet depth, shelf configuration, and whether you're storing ammunition separately all matter more than raw gun count. Best for: established collectors and households running joint FACs.
A cabinet at this size is a permanent fixture, so confirm floor loading and wall anchoring before ordering. Verdict: Buy only once your collection has stabilised near this size — oversizing wastes floor space in most Irish gun rooms.
Why gun safe capacity varies
A "5-gun" rating from one manufacturer doesn't always match another's, because the number depends on more than shelf count.
- Scoped rifles need more internal height and depth than the barrel-only measurement most capacity ratings assume
- Ammunition stored in the same cabinet reduces usable gun space, sometimes by a full tier
- Shotguns with longer barrels take up proportionally more vertical space than rifles
- Future FAC additions you haven't applied for yet still deserve a slot in your planning
- Available wall or floor space for anchoring often caps your realistic maximum before budget does
- Insurance minimum ratings can force a heavier-rated safe regardless of gun count
If your ammunition doesn't fit inside your firearm safe, a dedicated ammunition storage cabinet keeps both compliant without eating into gun capacity.
Is a 5 gun safe enough for one FAC?
A 5 gun safe covers most single-licence households in 2026, provided you're not also storing ammunition or a handgun in the same cabinet. It becomes tight the moment a second scoped rifle or a third shotgun enters the collection, so treat it as a starting point rather than a permanent ceiling.
Can I store ammunition in the same safe as firearms?
Ammunition can share a cabinet with firearms in many setups, but doing so reduces the usable gun capacity of that safe by a meaningful margin. Separate ammunition storage is worth checking against Ireland's gun safe insurance requirements before you decide, since some policies specify separation as a condition.
Does a bigger gun safe cost more to insure?
Safe size itself isn't usually the insurance factor — the security rating and lock type matter more than gun capacity. A correctly rated safe at the right capacity tends to satisfy policy conditions more cleanly than an undersized one crammed past its intended limit.
FAQ
What size gun safe do I need for 3 rifles?
A 3-5 gun safe covers 3 rifles comfortably in 2026, with one spare slot for a shotgun or a future addition. Scoped rifles need extra internal depth, so check that measurement rather than relying on the capacity number alone.
How many guns fit in a 5 gun safe?
A 5 gun safe fits 5 long guns when internal shelving is removed or adjusted for barrel length. Fitting exactly 5 scoped rifles is tighter than 5 unscoped shotguns, since scopes add height and width.
Is it better to buy a bigger gun safe than I need?
Buying one tier above your current firearm count is the standard recommendation for 2026 FAC holders, since it avoids a second cabinet purchase within a couple of years. Oversizing by more than one tier wastes floor space without adding real benefit.
Can a gun safe hold both rifles and shotguns?
Yes, most 6-10 gun safes are built to mix rifle and shotgun storage in the same cabinet. Longer shotgun barrels take up more vertical space, so factor that into which capacity tier you choose.
Do I need a bigger safe for a scoped rifle?
A scoped rifle needs more internal height and depth than the barrel-only measurement most capacity ratings use. If your collection is mostly scoped rifles, size up one tier from the flat gun-count recommendation.
Should ammunition be stored in a separate cabinet from firearms?
Separate ammunition storage is common practice in Ireland and preserves the full gun capacity of your firearm safe. Check your insurance policy, since some require ammunition kept apart from firearms.
What's the best gun safe size for a growing collection?
A 10+ gun capacity cabinet suits collectors adding firearms year over year, since it avoids repeat upgrades. Confirm floor loading and wall anchoring before ordering a cabinet at this size.
One last thing
Most buyers size a gun safe to their current FAC and forget the second application they're already planning. Buying the next tier up from the Griffon 5 gun safe now costs less than replacing a full cabinet, anchors and all, in 2026 or 2027 once the collection outgrows it.
