The Lockdown 15 Inch Cable Gun Lock earns our top spot for its California DOJ approval, meeting stringent safety standards for child protection. The robust steel cable threads through the action of rifles, pistols, and shotguns, rendering them inoperable while the non-marring coating protects firearm finishes. The keyed padlock provides reliable security without the complexity of combinations that children might accidentally discover.

What sets this lock apart is its universal compatibility across firearm types and its proven track record in safety compliance. The 15-inch length accommodates most firearms, and the green color provides visual confirmation of secured status. While keyed locks require keeping track of keys, the security tradeoff is worthwhile for child safety.

Pros
  • CA DOJ approved for legal compliance
  • Universal fit for rifles/pistols/shotguns
  • Non-marring protective coating
  • Simple keyed operation
  • Visual security indicator
  • Durable steel construction

Buyer's Guide

What to Look for in a Child Safety Lock for Gun Storage

California DOJ Approval

Look for CA DOJ approval as it indicates rigorous testing for child resistance. This certification ensures the lock meets legal standards for firearm safety in California, providing verified protection against child access.

Lock Type Selection

Choose between keyed locks for simplicity, combination locks for keyless convenience, or cable locks for universal fit. Keyed locks often provide better child safety as combinations can be discovered or accidentally left unlocked.

Firearm Compatibility

Verify the lock fits your specific firearms. Cable locks offer universal fit across rifles, pistols and shotguns, while trigger locks and safes may have size limitations requiring careful measurement.

Material Durability

Steel cables and hardened locks resist cutting and tampering attempts. Non-marring coatings protect firearm finishes while maintaining security. Look for cut-resistant designs for maximum child safety.

Portability Requirements

Consider if you need travel-friendly options like TSA-approved locks or portable safes for vehicle storage. Travel locks must balance accessibility for adults with impregnability for children.

Quantity and Value

Multi-packs provide better value for securing multiple firearms. Evaluate your collection size and storage locations before purchasing. A four-pack often costs less than three individual locks.
