Master Lock
Secure firearm storage is a legal requirement in many states and simple common sense everywhere else. Master Lock's gun locks — cable locks, trigger guard locks, and California-approved models — provide an affordable layer of storage security, and Impact Guns carries their padlocks and combination locks too for securing gear, cases, and safes.

Gun Locks: Cable and Trigger Guard
Master Lock's cable locks thread through a firearm's action or magazine well to physically prevent loading or firing, and their California-approved cable lock meets that state's specific storage requirements — relevant if you're shipping or selling to a CA buyer. The Adjustable Trigger Guard Lock takes a different approach, blocking the trigger directly rather than the action.
Keyed Alike: One Key for Multiple Locks
Master Lock's "Keyed Alike" gun locks (sold individually or in 3-packs) all open with the same key, which matters if you're securing multiple firearms and don't want to manage a separate key for each one. The Resettable Combination version skips keys entirely in favor of a combination you set yourself.
Padlocks and Combination Locks for Gear
Beyond firearm-specific locks, Master Lock's standard padlocks (Solid Body, Wide Covered) and TSA-Accepted combination locks are practical for securing a range bag, gun safe hasp, or travel case — the TSA-Accepted lock specifically allows airport security to open it without cutting it off during travel screening.
Frequently Asked Questions
Does a cable lock satisfy safe-storage laws in my state?
Requirements vary by state — a cable lock satisfies many states' safe-storage requirements, but some jurisdictions (including California) require specific approved models. Check your state's exact requirement, and note Master Lock's California-approved cable lock if you're in or shipping to that state.
Can I use a TSA-Accepted lock on a checked firearm case?
TSA regulations require that only you retain the key or combination for a firearm case — a standard TSA-accepted lock that airport security can open with a master key does not meet this requirement for firearm transport. Use a non-TSA lock for checked firearms.
