Best Lock Box for Flying With a Gun – 5 Picks by Lock and Weight

Lock box for flying with a gun: the deciding specs compared

A lock box for flying with a gun is chosen first by its lock: padlock holes you fill yourself, or a lock built into the box. Weight comes next, because the case rides inside your checked-bag allowance.

The table compares all five from maker and listing specs.

My padlock math: a shackle up to 0.46 in thick fits the Pelican, but the NANUK 909’s holes are 0.34 in, so measure your padlock before the trip. The lightest case saves about 2.3 lb over the heaviest.

The best lock boxes for flying with a gun, reviewed

Each lock box below was recommended by at least two independent top-ranking pages, and every spec comes from the maker or the Amazon listing. Owner notes come from maker review pages, forums and reviews I read; I have not handled these cases.

Pelican Vault V100 Hard Case: Best gun case for flying overall

3.7Best Safe Spec Score out of 5

• Security (lock and build)7/10
• Access (speed and ease)7/10
• Capacity8/10
• Value8/10

I scored security on the stiff polypropylene shell and big padlock holes (no independent burglary rating); access suffers a little because you must cut the foam, but the interior is the roomiest here for the money.

Praised for

• Fits a full-size pistol with several magazines, or two revolvers
• Sturdy shell and handle, with large lock holes

Common complaints

• The foam has to be cut by the owner; a sharp blade gives cleaner cuts
• One owner wanted an extra foam layer to fit a second pistol

Read on: Pelican: V100 Vault Small Pistol Case owner reviews (93 reviews) · USCCA Community: What safe for air travel?

Who it's for: A traveler flying with one full-size or compact pistol plus magazines who wants to choose their own padlocks; you cut the foam yourself, and the locks are not included.

The Pelican Vault V100 is a hard-sided polypropylene pistol case from Pelican, and it’s the one I’d hand most people flying with one handgun. Pelican lists an 11 x 8 x 4.5 in interior, a four-layer foam insert, push-button latches and stainless steel pins. The two padlock holes measure 0.46 in, the largest here, so you can use a sturdy non-TSA padlock with a thick shackle. Pelican calls it crushproof, dustproof and weather resistant, with an O-ring gasket and a purge vent. At 3.47 lb with foam it is the heaviest pick, and no locks come in the box. Owners on Pelican’s own page say a Glock 19X with three magazines, or two K-frame revolvers, fits well. The recurring gripe is the foam: it arrives solid, so you cut the gun shape yourself, and one owner wanted an extra layer for a second pistol. The Pelican Vault V100 is my default.

NANUK 909 Hard Case with Cubed Foam: Best waterproof gun case for flying

3.5Best Safe Spec Score out of 5

• Security (lock and build)7/10
• Access (speed and ease)7/10
• Capacity7/10
• Value7/10

I gave security a 7 for the resin shell and slide-locked latches (no burglary rating) and capacity a 7 because it is shallower than the Pelican; the small padlock holes limit which locks you can use.

Praised for

• Rugged build and quality foam insert
• Holds a pistol and three magazines with a custom foam cut

Common complaints

• One owner found the cubed foam not firm enough
• One owner wished the pre-cut insert matched his barrel length

Read on: NANUK: 909 Classic Gun Case owner reviews (25 reviews) · r/handguns: Recommendations for cases to travel by air with my handgun

Who it's for: A traveler with a compact or full-size pistol who wants a sealed case for flights and boat or truck trips; the 0.34 in padlock holes need a padlock with a thin shackle.

The NANUK 909 is a resin hard case from NANUK, and my pick when the case might sit in rain on the ramp. NANUK rates it IP67 waterproof and dustproof (the maker’s own claim) and fits an automatic pressure valve so altitude changes don’t vacuum-lock the lid. It weighs 2.16 lb empty, over a pound less than the Pelican, with an 11.4 x 7 x 3.7 in interior and PowerClaw latches that have slide locks. The catch is the lock holes: NANUK lists them at 0.34 in, so a thick-shackle padlock will not fit; buy a lock with a slim shackle and try it at home. Owners on NANUK’s page praise the build and say a pistol with three magazines fits once the foam is cut. One found the cubed foam not firm enough, and another wished the pre-cut insert matched his barrel length. The NANUK 909 is my wet-weather pick.

Vaultek LifePod 20: Best lock box with a built-in keypad

3.5Best Safe Spec Score out of 5

• Security (lock and build)7/10
• Access (speed and ease)9/10
• Capacity6/10
• Value5/10

Access earns a 9 because the keypad, backup keys and USB port cover every lockout; security is a 7 (polymer shell, no burglary rating), and the shallow interior and higher cost pull capacity and value down.

What owners and reviewers say review themes from 367 owner reviews, plus 4 posts and reviews we read

Praised for

• Sturdy build and the steel cable for tying it down
• Fits a full-size handgun with magazines for travel and the car

Common complaints

• The tray does not fit over a full-size gun, so check the depth first
• Some owners report surface scratches and foam wear

Read on: Vaultek: LifePod 20 owner reviews (367 reviews) · r/CCW: Test run for flying with my CCW

Who it's for: A traveler who wants one lock box for the flight, the hotel room and the car, with no padlocks to carry; it fits handguns up to 9.25 in long and needs a 9V battery for the keypad.

The Vaultek LifePod 20 is a polymer lock box from Vaultek with its own keypad lock, and I picked it for travelers who want no padlocks at all. A backlit keypad opens it, two backup keys cover a lockout, and a micro-USB port powers the keypad if the 9V battery dies. Vaultek says the 3.3 lb case is water resistant, airtight, dustproof and floats, fits firearms up to 9.25 in long, and meets TSA guidelines. A 48 in steel cable lets you tie it to the suitcase frame, a hotel bed or a car seat. The interior is only 2.125 in deep, and that is where owners trip up: one on Vaultek’s page found the tray no longer fits once a full-size gun is inside. Others mention surface scratches and foam wear. The Vaultek LifePod 20 also works in the car.

SnapSafe TrekLite Lock Box XL: Lightest lock box with a built-in combination

3.3Best Safe Spec Score out of 5

• Security (lock and build)6/10
• Access (speed and ease)8/10
• Capacity5/10
• Value8/10

I scored security a 6 because the polycarbonate box uses a TSA-keyed lock; the keyless combination makes access quick, the 2 in depth limits capacity, and the low weight and lifetime warranty help value.

What owners and reviewers say from 2 reviews and posts we read

Praised for

• Light and slim, so it barely adds to checked-bag weight
• Works in the truck, on a nightstand and at airport check-in

Common complaints

• A reviewer notes no lock box stops an airline from misrouting the bag

Read on: Field Ethos: SnapSafe TrekLite Lock Box review · Police1: SnapSafe GlideVault and TrekLite lock boxes

Who it's for: A traveler with one pistol (up to a full-size 1911) who watches bag weight and wants no padlocks; the built-in lock is TSA-recognized, which some owners prefer to avoid.

The SnapSafe TrekLite Lock Box XL is a polycarbonate gun lock box from SnapSafe, and my pick when bag weight matters most. SnapSafe lists it at 1.6 lb and 7 x 10 x 2 in, with a 4-digit combination lock (10,000 codes), a rubber over-mold, foam lining, room for a full-size 1911 and a 1,500 lb rated security cable. It uses a TSA-recognized lock: Field Ethos notes a TSA keyhole as the backup if you forget the code. TSA allows that, but if you don’t want a master key to fit, choose a padlocked case. SnapSafe’s own FAQ says the TrekLite is not California DOJ approved, even though one review I read claims otherwise; I go with the maker. Field Ethos’s one complaint is fair: no box stops an airline from misrouting the bag. The SnapSafe TrekLite XL is my lightweight pick.

Cedar Mill Fine Firearms Hard Pistol Case: Best budget gun case for flying

3.2Best Safe Spec Score out of 5

• Security (lock and build)5/10
• Access (speed and ease)7/10
• Capacity6/10
• Value9/10

Security is a 5 because owners say the thin plastic could be pried; easy pick-and-pluck foam helps access, and the low weight and price make it the best value here.

Praised for

• Much lighter than a Pelican in a checked bag
• Holds a Glock 17 or 19X with spare magazines

Common complaints

• One lock on one side let the case open from the other side
• A slide lock can bind, and a brand of TSA case lock had too short a pin

Read on: Cedar Mill Fine Firearms: Pick & Pluck Pistol Case owner reviews (507 reviews) · USCCA Community: What safe for air travel?

Who it's for: An occasional flyer with one pistol who wants the lightest padlocked case; the thin plastic suits a case packed inside a suitcase, not one checked on its own.

The Cedar Mill Fine Firearms Hard Pistol Case is a pick-and-pluck plastic pistol case from Cedar Mill, and I list it as the budget, weight-saving option. The Amazon listing gives 12 x 8 x 3.5 in and about 1.2 lb, the lightest here, with egg-crate foam in the lid and pluckable foam below, so you shape the cavity by hand. You add your own padlocks at two lock points. Owners on Cedar Mill’s store say a Glock 17 or 19X fits with spare magazines. The complaints teach the most: one owner found that a lock on one side still let the case open from the other side, a slide lock can bind, and one brand of TSA case lock had too short a pin. Another says a determined person could pry the plastic, so I’d pack the Cedar Mill case inside a suitcase.

Which lock box for flying with a gun should you get

• One handgun, your own non-TSA padlocks: Pelican Vault V100.
• Wet trips or boat-and-plane travel: NANUK 909, with a slim-shackle padlock.
• No padlocks, plus the car and hotel room: Vaultek LifePod 20.
• Lightest box with a built-in lock: SnapSafe TrekLite XL.
• Lowest weight and cost, packed inside a suitcase: Cedar Mill pistol case.

What TSA asks of a gun lock box in checked baggage

In general terms, the Transportation Security Administration (TSA) says an unloaded firearm may travel only in checked baggage, in a locked hard-sided container that completely secures it, declared to the airline at the ticket counter. The TSA firearms page adds that locked cases that can be easily opened are not permitted, and that the box a gun came in may not be secure enough. It also says you may use any brand or type of lock, including a TSA-recognized lock, and only you keep the lock and key (or combination) unless TSA asks.

Ammunition goes in an ammunition box made to carry it, and magazines must be boxed or inside the locked case. Airlines set their own limits and fees, and gun laws change at each state line, so check your airline, your destination’s laws and TSA’s page before every trip. This is general information, not legal advice.

TSA intercepted 6,678 firearms at checkpoints in 2024, about 94% of them loaded.

How to pack a gun lock box in a checked bag

A lock box for flying with a gun is packed and locked at home; you then declare it at the airline counter.

1. Unload the firearm and check the chamber and magazine well twice.
2. Fit the gun and magazines in the foam, with ammunition in a box made for it.
3. Lock every lock point on the case, or run the lock through the handle.
4. Place the case in your suitcase and loop the cable around the suitcase frame.
5. Keep the key or code with you, never in the bag.
6. At the ticket counter, tell the agent you are traveling with a firearm and sign the declaration.

Vaultek’s video below walks through declaring a LifePod at the counter.

Gun lock box problems owners run into when flying, and the fix

A lock box for flying with a gun usually fails at the lock or the packing, not the shell.

• “Will a TSA master key open my gun case?” It’s a recurring worry in USCCA forum threads and on r/handguns. TSA allows any lock, so if a TSA lock bothers you, use non-TSA padlocks on the Pelican, NANUK or Cedar Mill.
• The padlock doesn’t fit, or the lid opens from one side. An owner on Cedar Mill’s store warns: “make sure your lock doesn’t allow the case to be opened from the side.” Lock every point and test your padlock in the holes before you pack.
• The case could be lifted out of the bag. A USCCA instructor writes: “I use the cable to lock the case to an internal strut of the suitcase.” The LifePod 20 and TrekLite include a cable for that.
• The case eats your weight allowance. One USCCA member wanted “a little smaller and lighter safe.” The Cedar Mill (1.2 lb) and TrekLite (1.6 lb) save over 2 lb against the Pelican.

How we picked these lock boxes for flying with a gun

Every lock box for flying with a gun here is recommended by at least two independent top-ranking pages and sells as one in-stock Amazon US listing. The Pelican Vault V100 appears on 9MMMagazines, Top Firearm Reviews, a USCCA forum thread and r/CCW; the NANUK 909 on r/handguns and Handguns magazine; the LifePod and TrekLite on the USCCA travel guide, plus 9MMMagazines and Field Ethos for the TrekLite; the Cedar Mill on three of them.

From our notes: The 0.12 in gap between the Pelican’s 0.46 in padlock holes and the NANUK’s 0.34 in holes is the detail I’d have missed without reading the maker spec sheets side by side. No ranking page mentions it, yet it decides whether the padlock already in your drawer works. Picture someone packing the night before an early flight, discovering the shackle won’t go through. That scenario is why the table lists hole size first, and why I’d try the lock at home.

None of these cases makes a fire claim; they are travel cases, not safes. For storage at home, see my pistol safe picks, and for passports and cash on the road, my travel safe guide.
