The Master Lock No. 90KADSPT Keyed Trigger Lock is a steel and zinc constructed safety device designed to secure firearms during storage or transport. Built with a robust 4-pin tumbler cylinder mechanism, this trigger lock prevents unauthorized access and accidental discharge by physically blocking the trigger mechanism. The keyed design ensures that only authorized users with the correct key can remove the lock, making it an essential tool for responsible firearm ownership, compliance with storage mandates, and maintaining control over access in multi-person households or facilities.

The lock features protective rubber pads on its contact points, a critical detail that prevents marring or scratching to firearm finishes during extended use. The steel and zinc body construction delivers corrosion resistance and durability across varying storage environments, from climate-controlled safes to field equipment bags. The 4-pin tumbler cylinder provides adequate security for standard storage applications without requiring electronic components or batteries, ensuring reliability regardless of environmental conditions. At 0.5 lbs and compact dimensions of 3.9 x 3 x 6.7 inches, the unit remains portable enough for transport while maintaining a secure mechanical lock mechanism.

This Master Lock trigger lock suits anyone requiring a straightforward, mechanical firearm safety solution—from law enforcement officers securing duty weapons during administrative time, to civilian gun owners implementing layered storage security, to range safety officers maintaining control over facility equipment. The keyed trigger lock serves as an independent safety layer that complements other storage methods and meets many state and local firearms storage requirements. This product is ideal for those prioritizing simplicity, reliability, and finish protection over complex mechanisms or electronic dependencies.

Trigger locks represent an industry-standard approach to interim firearm security, particularly in settings where quick access is balanced against storage safety. The mechanical design of keyed locks eliminates compatibility concerns common with cable locks and avoids the battery dependency of electronic options. Master Lock's established position in the security lock market brings manufacturing consistency and availability of replacement keys, practical advantages for long-term ownership.
