Posted by AJ Koenes on Sep 2nd 2022

TSA locks are a great way to secure your firearm while traveling. Until recently only non-TSA locks were permitted, but recent changes in the regulation have opened the door for many possibilities for securing your handgun on an airplane.

Ensuring your firearms are secure while traveling is crucial, and the right lock makes all the difference. Here, we present the top 5 TSA-approved locks for your gun case. Whether you're traveling with weapons or other valuables, using TSA-approved locks ensures compliance with Transportation Security Administration regulations and peace of mind.

Traveling with a firearm can be daunting for many, but it's more common than you might think. Whether you're heading out on a hunting trip, transporting a family heirloom, or traveling for business, knowing how to properly secure your firearm is essential. Until recently, firearms had to be stored in a hard-sided case with locks controlled only by the owner. TSA agents would require the owner to unlock the case for inspection.

However, recent changes in regulations now allow the use of TSA-certified locks. This guide provides you with the best options for TSA-approved locks and other reliable locks to secure your firearms during air travel. Ensure your next trip is worry-free by choosing the right lock to protect your valuable gear.

You can buy it on:

MSRP: $7.99

The Master Lock No. 140 is a traditional padlock known for its robust security features. Its U-shank design offers enhanced security compared to cable locks, making it a reliable choice for securing firearms and other valuables.

  1. Hardened Steel Shackle: The shackle is made of hardened steel, providing resistance to physical attacks and enhancing durability.

Although not TSA approved, the Master Lock No. 140 complies with regulations and is often preferred for firearms transportation. The longer U-shank can lead to gaps in certain cases, potentially allowing a firearm to be slipped out. To avoid issues at the airport, it’s crucial to test the lock with your case before traveling.

Additionally, cable locks are generally easier to defeat compared to more rigid lock types.

Overall, the Sure Lock Combination Cable Lock is a practical choice for those seeking an easy-to-use and readable lock, though its cable design may not be suitable for all security needs.

Final Thoughts

When it comes to firearm security, selecting the right TSA-approved lock is crucial. While using a TSA lock is not mandatory, millions of travelers rely on Travel Sentry locks without issue. Ensuring your rifle, pistol, or revolver is protected from theft and damage is paramount. Single shank locks offer a secure fit for most cases, effectively preventing the firearm from slipping out of the case. U-shank locks have a proven track record of being effective, user-friendly, and secure, although their widespread use has led to common defeat methods. Cable locks, while versatile, are the least secure option, and trusting an expensive firearm to a thin cable can be risky.

TSA-approved locks are designed to be accessible by TSA agents nationwide using a universal key. With this understanding of the different lock types, choose a lock that not only fits your budget but also guarantees the safety of your firearm during travel. Prioritize security to ensure your valuable firearm remains protected at all times.
