Quick Answer: Costco.com sells gun safes from five sources — Bighorn, Cannon, Winchester, ProSteel (Browning’s parent brand), and its own Sanctuary house brand — ranging from a $89.99 GunVault handgun micro-vault up to a $1,699.99 Cannon Landmark CS5950 rated for 80 guns. Two things make Costco different from other big-box retailers: you need an active paid membership to buy anything on Costco.com, and freight-delivered items like full-size gun safes are limited to roughly 50 miles of a physical Costco warehouse. Sanctuary itself isn’t an independent manufacturer — it’s made by SA Consumer Products, the same company behind the Sports Afield safes already sold elsewhere.
Costco’s gun-safe listings pull over 6,600 monthly searches from shoppers comparing warehouse-club pricing against Amazon and specialty safe retailers. We pulled brands, models, and pricing straight from Costco’s own product pages and confirmed the membership and delivery restrictions that don’t show up until checkout.

Bighorn SafeX 15.05 cu. ft.
- Costco's most-reviewed full-size gun safe, with interior LED lighting and a built-in electrical outlet for charging a dehumidifier rod or trickle charger — see our gun safe dehumidifier picks if you're pairing one.
- 341 lbs and 55.7"H x 29"W x 22"D, sized for a closet or garage corner rather than a dedicated gun room.
- Bighorn also sells larger SafeX models (23.12 and 25.2 cu. ft.) through the same Costco listing page for buyers who outgrow the 15.05.
A full-size safe like this ships freight, not by mail — if you’re also stocking up on lighter accessories like a bolt-down kit or a lock box, it’s worth starting a free 30-day Amazon Prime trial so those smaller items arrive in two days while the safe itself is scheduled for delivery.
Sanctuary Reserve (Costco house brand)
- Sanctuary isn't an independent gun-safe manufacturer — it's made by SA Consumer Products, the same company behind the Sports Afield safes this site already reviews, sold as a Costco-only house-brand line.
- Worth knowing before you buy: SA Consumer Products recalled the small $75-$100 Sanctuary Quick Access Biometric Home Safe in 2024 after 77 reports of the fingerprint lock opening for unauthorized users. That recall covers a separate handgun-sized personal safe, not the larger Reserve-series fire-rated gun safes on this page, which use a standard electronic keypad rather than the recalled biometric mechanism — but it's a fair question to ask if you're comparing Sanctuary's biometric handgun safes specifically.
- Sizing runs smaller than Bighorn or Winchester at a comparable price point, which makes sense for buyers who want fire-and-water protection for a modest collection rather than maximum capacity.
Winchester Ranger 42
- A genuinely different Winchester line from the Legacy 53 and Bandit 14 models this site covers in our Winchester gun safe roundup — the Ranger 42 is sized and priced specifically for Costco's warehouse-club channel.
- 1,624 lbs and 59"H x 46"W x 27"D — check your local warehouse's freight-delivery radius before ordering; see the membership and delivery notes below.
- Costco also lists the larger Winchester Legacy 53 (52.4 cu. ft., 2.5-hour fire rating, 10-gauge steel with a 1/4" door plate) for buyers who want the longest fire rating in Costco's lineup.
The membership and delivery catch
Two restrictions apply to a Costco gun safe that don’t apply at Tractor Supply, Home Depot, or Amazon. First, Costco.com requires an active paid membership to complete any purchase — there’s no guest checkout, so the effective price of a Costco safe includes at least a $65/year Gold Star membership if you don’t already have one. Second, Costco’s own delivery terms limit freight-delivered items — which includes every full-size gun safe on this page — to roughly 50 miles of a physical Costco warehouse, with extra charges and exceptions for Alaska, Hawaii, and Puerto Rico. If you don’t live near a warehouse, a safe that shows as in-stock online may simply not be deliverable to your address. For general freight-delivery logistics on a heavy safe, see our gun safe delivery guide.
Should you buy from Costco, or elsewhere?
Buy from Costco if you’re already a member, live within delivery range of a warehouse, and want warehouse-club pricing on a recognizable brand like Bighorn or Winchester. Look elsewhere — Amazon, Tractor Supply, or the brand direct — if you’re not a member, live outside the roughly 50-mile delivery radius, or want the full size range within a single brand’s catalog rather than the handful of SKUs Costco carries (see our Winchester and Sports Afield roundups, plus our Tractor Supply gun safe guide, for what those brands sell beyond Costco’s lineup).
The bottom line
Costco.com carries a real, if narrow, gun-safe lineup — Bighorn, Cannon, Winchester, ProSteel, and its own Sanctuary house brand — with prices from $89.99 for a handgun micro-vault up to $1,699.99 for an 80-gun Cannon Landmark. The catch isn’t the hardware, it’s the checkout: you need a paid membership, and delivery only reaches about 50 miles from a physical warehouse. If either of those rules you out, the same brands are available on Amazon with no membership required.
