Gun Case Lock For Air Travel – No TSA Approved Locks Here

Here you go on your travel adventure with your firearm in tow. And you know, when traveling by plane with a firearm, you must store it in a locked, hard-sided case as part of the TSA guidelines. So the only thing you need now is a suitable gun case lock for air travel. But what kind of lock do you use?

There is a lot of talk about TSA approved locks for suitcases, but can you use one on a gun case?

TSA-approved locks allow TSA officers to open the lock if they need to inspect your checked bags further. For example, if you use a padlock with the Travel Sentry red diamond logo, you allow the TSA officer to open the lock with a TSA master key to inspect your luggage further.

However, TSA-approved locks DO NOT apply to gun cases. Therefore, you cannot use TSA-approved locks for the firearm case. We’ll tell you why in a bit.

Why Do You Need Gun Case Lock For Air Travel?

Why do you need a gun case lock for air travel is a great question. The primary reason is to ensure no one has access to your gun.

Another reason is to protect all the passengers on the plane. After all, you don’t want anyone to use your firearm to harm others.

With this in mind, TSA requires a lockable, hard-sided case for an unloaded gun in checked baggage. The gun case must completely secure the rifle. TSA prohibits easily accessible weapon containers. Only you – the passenger, must have the gun case key or lock combination. If requested, you will open the hard-sided gun case for TSA inspection.

Why Not Use A TSA-Approved Gun Case Lock For Air Travel?

You can’t secure the firearm in the gun case if you use a TSA-approved lock. Unauthorized access to the gun is possible with a TSA master key or tool. TSA requires a gun case lock for air travel that will keep the firearm secured in the case. TSA-approved padlocks undermine handgun case security. Therefore, you cannot use a TSA-approved lock for your gun case.

So, it’s clear that when flying with a firearm, you can use ordinary but heavy-duty locks to secure your gun case.

The size of the gun case lock for air travel will depend on the size of the lock ports. The padlocks that usually fit most firearm cases are those with a shackle diameter of less than 9.4 mm (3/8 in).

What To Look For When Buying Gun Case Lock For Air Travel

When selecting a gun case for air travel, it is important to ensure that the padlocks used to secure it are strong. Weak padlocks can lead to unauthorized access to the firearm and potential misuse.

When this happens, you violate TSA guidelines on transporting firearms and endanger the people around you.

Here are three things to consider when buying a gun case lock for air travel.

Number Of Pins

The tumbler cylinder of each lock has a different number of pins. If the padlock has more than one pin, each pin must reach a certain height for the padlock to open. Therefore, the more pins a padlock has, the harder it is to open with something other than the key.

Lock Body And Shackle Materials

You need a gun case lock for air travel made of solid, sturdy materials to protect a valuable item like a gun. Heavy-duty lock bodies of stainless steel, titanium, solid hardened steel, TPE elastomer, or laminated steel are durable and long-lasting. Hence, they are highly resistant to the harshest conditions.

Materials like boron-carbide steel are perfect for padlock shackles because of their hardenability properties.

Thick shackles are hard to cut, so they are better. But thick locks will not fit into the lock ports or holders on the gun case. Most gun cases have lock holes that are 9.4mm in diameter. So any padlock with a shackle less than 9.4mm in diameter will work for your gun case.

Resistance Against Cutting, Prying, Picking, And Sawing

TSA advises using secure locks for storing firearms – the locks should be difficult to open, unbreakable, and safe from picking or prying.

A gun case lock suitable for air travel should be able to resist and endure forceful attacks without compromising the security of your firearm. A padlock has to hold up against impacts or strikes to protect your weapon.
