Master Lock 90KADSPT Universal Adjustable Trigger Guard Lock, Keyed Alike, Blue Steel/Zinc, Fits Most Firearms

The Master Lock 90KADSPT is a universal adjustable trigger guard lock built for responsible firearm storage and quick-access security. Whether you're a hunter managing multiple firearms, a shooter with a home arsenal, or a gun owner who wants a simple mechanical safety layer, this keyed trigger lock fits most firearms and keeps your trigger guard secured when the gun isn't in use. It's the kind of no-fuss security solution that experienced shooters trust for everyday peace of mind.

Built from steel and zinc for long-term durability, the 90KADSPT uses a 4-pin tumbler cylinder—the same reliable mechanism in Master Lock's padlocks—so you get proven locking performance in a firearm-specific form. The adjustable design means one lock works across different trigger guard sizes, making it practical whether you're securing a rifle, shotgun, or handgun. Each lock comes keyed alike, letting you use a single key across multiple guns if you choose.

One detail that matters on the range and in the field: protective rubber pads grip the trigger guard without marring your gun's finish. Whether your firearm has a polished blue, hard-anodized aluminum, or any other surface you've invested in, these pads keep scratches and dings out of the equation. It's a small feature that reflects the engineering of a company that's been making locks for over a century.

Frequently Asked Questions

What firearms does the Master Lock 90KADSPT fit?

The 90KADSPT is designed as a universal adjustable trigger guard lock that fits most firearms, including rifles, shotguns, and handguns with standard trigger guard designs. The adjustable mechanism accommodates different trigger guard sizes, but if you have an unusual or particularly compact trigger guard, it's worth checking the dimensions before purchasing.

Will this lock scratch or damage my gun's finish?

No. The protective rubber pads on the lock grip the trigger guard without metal-to-metal contact, protecting your firearm's finish from marring, scratching, or other cosmetic damage during storage or repeated use.

What does "keyed alike" mean?

Keyed alike means all the locks in your set (if you buy multiples) use the same key, allowing you to manage security across several firearms with just one key. This is convenient for hunters or shooters with multiple guns.

Is this lock weatherproof for outdoor storage?

The steel and zinc construction is designed for durability and resistance to corrosion, making it suitable for standard outdoor or field use. For extended exposure to extreme weather or salt environments, periodically check the lock for rust and apply a light coat of oil if needed.
