Buying Guide

Choose the right locking mechanism

Combination locks avoid key management while keyed locks can be simpler to operate; decide based on who will access the firearm and how quickly

Check compatibility with your firearm

Trigger-style locks should fit the trigger guard and action of pistols, rifles, and shotguns, while cable locks are more versatile for threaded barrels and long guns

Prioritize visible, tamper-resistant construction

Look for hardened steel or coated metal shackles and durable housings to resist tampering and protect finish

Consider regulatory approvals

If local law or storage requirements matter, select locks with compliance tags such as CA DOJ approval for use in regulated jurisdictions

Factor in ease of use and code management

For combination locks, choose readable dials and reliable resetting procedures; for keyed systems, consider keyed-alike options to reduce key count
