RioRand Keyed Alike Trigger Lock, 3-Pack

Best for households with multiple firearms needing quick, uniform access. This keyed-alike design uses identical keys for all locks, reducing key management. It includes two brass spare keys to prevent lockouts when keys are misplaced. The adjustable ratchet fit accommodates most standard trigger guards, providing steady security during home storage, cabinet placement, or range transport. Soft rubber padding protects firearm finishes from scratches during use and storage. Choose this for simple, unified access across several guns; avoid if any trigger guard is oversized beyond the lock’s adjustment range.
Master Lock Black Gun Trigger Lock, 3-Pack

Best for users who want global standard design and high durability. This set uses a steel and zinc body with a positive locking mechanism and adjustable ratchet, ensuring robust security against tampering. The 3-pack format suits owners with several pistols or long guns. It’s a solid choice for basic household safety, gun cabinets, or range storage. A potential limitation is that some users may prefer keyed-alike simplicity if managing many locks; otherwise it offers strong, simple protection.
RioRand 3-Digit Combination Trigger Lock

This 3-digit combination lock is best for users who prefer password-style security without carrying keys. It ships preset and allows easy code resets with the included tool. Soft rubber pads protect finishes, and the lock is designed to fit most standard straight trigger guards. Not suitable for oversized or uniquely shaped guards. Best for quick access in a dedicated safe or cabinet where remembering a code is convenient.
RioRand Keyed Alike Trigger Lock, 5-Pack

Best for larger households or gun-owners with multiple firearms needing uniform access. This keyed-alike set includes two spare keys per lock to avoid access issues from lost keys. The adjustable ratchet provides a secure fit across most standard guards, with rubber padding to minimize muzzle or trigger-guard finish damage. Choose this if you want consistent keying across many locks; beware of limited compatibility with unusually shaped guards or oversized triggers.
NJMK Trigger Lock, Set of 5

Best for budget-conscious buyers needing multi-gun protection. The NJMK set claims easy attachment and a secure adjustable ratchet for a universal fit. It’s marketed for handguns, hunting guns, shotguns, and revolvers, offering broad compatibility. The material quality appears solid for everyday storage, but as with any bulk set, verify fit on your specific firearm models before full deployment. If you own non-standard guards, test sizing early.
