Allen 18511 Trigger LockOpen With Key Red Polymer Firearm Fit- Handgun

The Allen 18511 red polymer trigger lock provides a straightforward way to secure handguns and revolvers when they're not in use—whether you're storing them safely at home, in a vehicle, or during transport. This universal trigger lock fits most handgun and revolver designs, making it a practical addition to your firearm safety routine without requiring a safe or safe room. The bright red polymer construction is easy to spot and keeps you aware of its presence, reducing the chance of an unintended discharge.

Installation is simple: position one side of the lock on each side of the trigger, seat the post behind the trigger guard, and use the included key to tighten the security screw until it sits flush with the lock body. Once installed, the trigger is mechanically blocked and cannot be pulled. The key-operated design means only someone with the key can remove it—no combination to forget, no batteries to replace.

This trigger lock is designed for handguns and revolvers with triggers positioned toward the rear or middle of the trigger guard. It's not suitable for lever-action rifles or firearms with forward-positioned triggers. If you're serious about responsible gun storage and want a dependable mechanical lock that works with your carry gun, duty gun, or home defense handgun, this Allen lock delivers proven security at a reasonable cost.
