Master Lock Black Gun Trigger Lock 3 Pack - Keyless Safety

Our review of the Master Lock Black Gun Trigger Lock 3 Pack finds it best suited for gun owners who want a simple, durable, and keyless way to block the trigger on pistols and rifles. The single biggest reason to buy is its combination of solid construction and easy reprogrammable 3-dial code, which delivers straightforward firearm safety without keys or complicated installation. For households worried about child access or for owners who need a basic transport and storage safety device, this trigger lock offers practical protection at a modest price.

Key Features

• Set your own combination: The 3-dial combination system provides keyless convenience and lets each owner choose a memorable code for daily use.
• Durable construction: A steel and zinc body gives the lock a sturdy feel and resists bending or forced entry attempts during typical use.
• Positive locking mechanism: The adjustable ratchet mechanism ensures a tight, reliable lock around the trigger guard for consistent security.
• Protective rubber pads: Soft pads on the mating surfaces prevent marring or scratching of firearm finishes while the lock is installed.
• Limited Lifetime Warranty: Backing from the manufacturer provides added peace of mind and confidence in long-term reliability.

Who It's For

The Master Lock trigger lock is aimed at practical gun owners who need a no-fuss safety device for home storage, short-term transport, or to keep firearms out of reach of children. It is especially useful for owners who prefer a keyless combination over a keyed lock so they do not have to manage a separate key.

Those who need a concealment-grade or ultra-high-security safe should look elsewhere, as this device is designed as a safety and deterrent rather than a full replacement for a dedicated firearm safe or heavy duty cable lock for long-term unattended storage.

Pros & Cons
