Choosing the right gun lock protects your household, prevents unauthorized use, and meets legal or travel requirements. This guide highlights top gun-lock options across budgets and use cases. Recommendations are based on extensive research, hands-on testing, and expert and consumer feedback to help you pick the right safety solution.
How we tested and decided
- Security & build: We evaluated materials, locking mechanisms (trigger, cable, combination, biometric), and resistance to prying or cutting. Certifications such as TSA or DOJ approval were verified where applicable.
- Real-world use: We tested ease of installation, one-handed access, travel suitability, and whether devices damage firearm finishes.
- Speed & reliability: For biometric models we measured enrollment ease, unlock speed, and false-rejection rates across multiple users and environments (low light, sweaty fingertips).
- Compatibility & fit: Each lock was checked against common pistol and rifle designs and case types.
- User feedback & reliability: We surveyed verified buyer reviews and consulted expert sources for long-term reliability and common failure modes.
- Value judgment: Price, included accessories (keys, cables, mounting hardware), and warranty/support factored into final rankings.
Universal Trigger Lock
An ultra-affordable, straightforward trigger lock that fits most handguns and revolvers. Durable composite construction, easy installation with included key tool, and a flush security screw deliver basic, reliable protection for owners who need a no-frills child-safety solution.
The Allen Company Universal Trigger Lock is the best low-cost entry for basic firearm safety. It’s a lightweight composite trigger lock with a security screw that sits flush to avoid snagging and a small key tool included for quick access. It won’t replace a safe or a cable lock for long-term storage, but for responsible gun owners who need an inexpensive, portable lock that won’t mar finishes, it delivers solid performance. Pros: extremely affordable, simple to use, compact. Cons: not cut- or pry-proof like heavier metal locks and not ideal as a sole long-term storage method.
ONNAIS Trigger Rack
A premium one-hand-access organizer with a biometric trigger lock and removable safe module. It combines quick home-defense access with tray organization for phone, watch, and everyday carry—ideal for bedside security and travel-ready concealment.
The ONNAIS Gun Rack Trigger Lock is a premium, multi-function bedside organizer and biometric trigger lock. Its vertical ergonomic design positions the firearm naturally against a fingerprint sensor and backlit keypad for fast access. The handgun module is detachable for travel and weighs roughly as much as a pistol—handy for hotel stays or vehicle storage. Build quality is attractive and the tray keeps EDC items organized. Technical notes: ergonomic vertical orientation, biometric + keypad, not compatible with weapon lights. Pros: rapid access, integrated EDC tray, travel-friendly removable safe. Cons: higher price point and larger footprint than a standalone cable or trigger lock.
TSA Case Combo Set
A practical two-pack of TSA-approved 4-digit combination locks designed for gun cases, ammo boxes, and travel. Durable zinc alloy construction, resettable codes, and broad compatibility make this a smart mid-priced choice for shooters who travel.
Kinghardcase’s TSA-approved 2-pack delivers excellent utility for the traveling shooter. The zinc-alloy housing and iron locking hooks give a feeling of solid security while the red diamond TSA approval means agents can inspect luggage without damage. The 4-digit combination is user-resettable and setup is straightforward. These locks work well on hard cases, rifle/handgun cases, and ammo boxes — a practical alternative to keyed locks for frequent travelers. Pros: TSA-compliant, resettable code, versatile fit for cases and boxes. Cons: not intended to secure a firearm against determined theft when left unattended for long periods (use a full safe for that purpose).
AINIRO Biometric Mount
A responsive biometric trigger-style lock and wall-mount system that stores up to 50 fingerprints. Combines display-grade presentation with fast access and durable aluminum construction—great for enthusiasts who want secure display and quick retrieval.
The AINIRO Biometric Gun Trigger Lock stands out as an editor’s pick because it balances security, speed, and presentation. The aluminum-alloy body, rubber padding, and high-resolution 508 DPI sensor provide a smooth, non-marring mount and fast fingerprint access. With space for up to 50 scans and three unlocking modes, it’s flexible for families or range shops. The wall-mount option turns firearms into a secure, stylish display while protecting triggers and preventing accidental discharge. Pros: fast, reliable biometrics; high-capacity fingerprint storage; attractive mounting. Cons: pricier than basic locks and requires a consistent power/battery source for biometrics.
